Megamorph →Used Deck

Comprehensive evaluation: It is highly convenient to be able to both strengthen and weaken, and if you make a combo that makes use of both, is it within sight of a one-turn kill?
If your LP is low, equip it to your monster, and if your opponent's LP is low, equip it to your opponent's monster to gain an advantage in battle.
There are few situations where you can't use it because it's not just strengthening or weakening.
Furthermore, you can aim for great damage by making use of both strengthening and weakening.
Using his enhanced ATK of the opponent's monster to deal damage reduces the opponent's LP, bringing it to half.
For example, if you double the opponent's ATK and use Dimension Reflector to deal damage that refers to his ATK, you can attack the halved monster with Dimension Reflector and win.
If you use it against his original ATK of 3000, you can win in one turn with 6000 effect damage and 4500 battles damage.
Other than that, like Amazoness Swords Woman's suicide attack.
Since the search is effective, it is easy to set up combos.

In the game work, it is a card positioned as "a handy and convenient strengthening spell that can strengthen any monster" including chimeras that are eerily combined like construction monsters. It used to be a card that more than doubled the stats of monsters, but it has a history of decreasing from 1000 to 500 to 300 each time it was included in later games.
In True DM, the key to clearing the game was how quickly this card, which was stolen from Pegasus, was attached to Meteor Black and Skull Knight, which was stolen from the Prairie Priest.
In the OCG, this card is also a pretty dynamic Equip Spell that halves the equipped monster's ATK if he is superior in his LP value, and doubles it if he is inferior.
The main usage is to effectively reduce your own LP with monster effects and Spell / Trap costs, attach this card to a large monster that comes out like that, and run over it with a single blow with its doubled ATK. However, since it can also be equipped to an opponent's monster, it can also be used to weaken the opponent's monster, double the ATK of the opponent's monster, and use effects that refer to that ATK to raise the RBI of your monster or deal burn damage. .
Even if you are superior or inferior, the effect will be applied without problems even if the LP difference is only 100, and your LP is 2000 or less, or the LP difference between each other is 3000 or more. There are no extra orders or activation costs such as 0 battle damage, so I think it's still a good Equip Spell that is worth using for both strengthening and combo purposes.

I think that Devil Franken → Ultimate Dragon → Gigantic is the old-fashioned famous one kill. It can also weaken the opponent, and it is also a surprisingly dexterous card.

The venerable equipment that first appeared in the very first duel in the original work.
As the name suggests, it can double the RBI of the equipped monster under certain conditions, and the higher the RBI, the stronger the monster.
However, if your LP is lower than your opponent's, it has the disadvantage of being halved if it is higher. If you inflict a lot of damage on your opponent with the equipped card, that situation is likely to occur, so you want to decide the match at once. It works well with cards that require an LP cost due to their characteristics.
However, since this card does not specifically specify the target to be equipped, it can be equipped to the opponent, and if you are in a situation where his LP is advantageous, you can use it as a weakening card.
In addition, you can dare to strengthen the opponent's monster and use it together with a monster that gains his ATK of the opponent's monster to get a tremendous hit point. After that, if you remove the giant growth, you can expect a lot of damage due to the hit difference.
I think it's a deep equipment with hidden combos that you wouldn't expect to see in the early days because it's hard to perish.

Exciting card that doubles or halves by referring to LP
It's also excellent as a one-kill part, and even if the opponent's LP is lower, you can equip it to the opponent's monster and halve it, so it's good that it doesn't spoil.

A card that shines in a pinch. In addition, if you equip it on your opponent, you can make use of the disadvantages of the second half and it is delicious.

With his LP-paying cards like Cyber-Stein and Demis, and high RBI monsters, you can get 1 kill.

Onekill's friend.
He works well with decks that pay LP or use 《Upstart Goblin》etc. to one-kill decks that have a difference in LP while preparing.
If you equip it on a continuous attack type monster, you should be careful about how the opponent's LP is reduced, otherwise it will weaken and you will not be able to finish it off.
It's hard to put it in his normal deck because it's hard to be influenced by each other's LP, but even if he has a lot of LP, he can be weakened by equipping it to the opponent, so it's surprisingly hard to spoil.

A time-honored and powerful equipment card that has been a companion to one-kill since ancient times.
Although it is unstable, the power of permanent doubling with one card is overwhelming, and it is excellent that anyone can equip it regardless of the theme or even the race. Since it can also be equipped on the opponent, it will not spoil in any situation, but if he misreads his LP, it will be a mass of disadvantages, so you need to be careful when using it.

When his LP is lower than yours, equip it to your own monster to double his ATK, and when your own his LP is higher, equip it to your opponent's monster to halve his ATK, allowing for flexible operation. A reliable card. In the game, Kaiba had a series of one-kills with the ultimate dragon from Devifla, but in reality it didn't go so well.

It's so big.... (*However, only when his LP is less than his opponent's)
An equipment card that doubles his ATK when his LP is less than his opponent's.
It goes without saying that double ATK is as powerful as Limiter Removal.
However, if his LP is higher than his opponent's, his ATK will be halved.
In this case, you want to equip it to your opponent's monster.
It is forbidden to say that it has not become huge.

It was also famous as a companion for Debifla, Demis Dozer, and 1 kill.
It was simply excellent as a power card and was in the limit.

It's erratic in that it's an Equip Spell and depends on LP, but it has an explosive effect.
If you use it as a normal power-up card, the moment the opponent's LP falls below his LP, the equipped monster will power down at once, so if you use it, you'll want to consider a one-hit kill.
Now that Devil Franken has been eased into restrictions, things like the old fashioned Devil Hula Wan Kill can also be done.

He gets stronger the more inferior he is...
The perfect card for such a hero! Gigantic!
Together with contraction, you can play Doraemon's light play!
This is his Equip Spell and over there is his Quick-Play Spell.

I'm a power supremacist, so I love cards like this.
If you have LP, it's also a point to halve it

1 kill let's go ^p^
A perverted card that makes you happy when your LP is lower than your opponent's.
Even if your own is expensive, you can use it to equip your opponent.
However, since it's an equipment card after all, I'd like to prepare properly so that the monster is not removed.

Accompanied by 1 kill. Depending on the LP situation, you can also take the tactic of equipping the opponent and destroying it in battle, so its strength is quite good. Of course, there are weaknesses due to the Equip Spell, but the definite explosive power is still alive and well.

His Equip Spell that spawned his Decks like Demis Dozer and Devil Franken 1 Kill. Since the effect changes depending on the LP situation, it cannot be adopted simply because it can expect a high RBI.
However, if you have a lot of his LP, you can equip it to your opponent and weaken it, so basically it won't spoil.

An equipment card that doubles or halves ATK depending on LP.
When his LP is low, he can be used against monsters with over 4000 ATK to kill them on the first turn, but in the opposite situation, it can also be used to equip opponent monsters to assist in battle.
It is one that is often used to accompany a one-turn kill.

An Equip Spell that has been around since the early days.
Performance changes depending on LP, so it can't be said to be stable, but it's perfect for those who want a one-kill finish with a powerful monster.
Of course, Deck is not chosen, but it is a strong ally of romantic Deck.

A time-honored Equip Spell that has been around since the beginning. Although it is made into a card in the second term for the speed of the original appearance.
His Equip Spell with the effect that his ATK of the equipped monster is doubled if his LP is lower than the opponent's, and halved if it is higher.
His ATK double effect is representative of Yu-Gi-Oh, along with "Limiter Removal", and it is also a very loose condition with only one condition that his LP is lower.
Due to the nature of the late effect, this card is exclusively for finishing. Also, when you're in the upper hand, it's fun to equip your opponent's monsters with pseudo-shrinkage. In this case as well, I want to aim for immediate battle destruction.
Due to its powerful effect of doubling ATK, it is a favorite of one-kill Decks, and it is excellently compatible with Decks that utilize LP-paying effects such as Demisdozer and Devifla 1-kill. Therefore, the card had a lot of experience in regulation.

A romantic card that is irresistible to power idiots.
Equip Spell - If you have an advantage, it will be halved, so the risk is quite high.
