Double-Edged Sword →Used Deck

Equip this to your opponent's monster with ATK 2000 or more, and hit it with "Raphion, the Timelord" to get a one-kill.
Other than that, you can use 《Colossal Fighter》to attack infinitely and aim for a draw.

It is an Equip Spell that can enhance ATK by 2000 on any monster as long as it can receive the effect, regardless of the type of enemy, ally, or monster. A fragile double-edged sword that is attached, and if the battle damage received at once is 2000 or more, it will be sent to GY.
However, by equipping it to a monster that has the effect of making the opponent take the damage to you caused by battle, you can push the battles damage received by each other only to the opponent, simply doubling the battles damage inflicted on the opponent. You can also prevent this card from self-destructing.
Until now, it was a card that synergized only with some monsters such as "Amazoness Swords Woman" and Sphere, but in 2022, due to the two elements of Equip Spell and battle damage reflection, "Mikanko" cards that are compatible with this card on a theme basis will be released. With the appearance of , it has become a powerful card as an Equip Spell to choose there.
I quite like the composition of a new theme like this + one existing card that is very compatible, but in most cases such cards originally have a certain amount of potential, and it can be said that this card did not leak out. .

If you use it normally, the disadvantage is severe, so it stops at 5 points, but because it also gives you battle damage, it works well with monsters that have the effect of reflecting it.
An interesting card that probably won't be used in the environment, but has romance and some practicality.

An Equip Spell that has an exceptional increase value of 2000, but has two demerit effects. However, due to one of the disadvantages that should be balanced, it has become a problem card that is abused.
The first thing that comes to mind is when the opponent's LP is considerably reduced, equip it to the opponent's high ATK monster and use it like an old destruction ring to finish by self-destructing.
《Amazoness Swords Woman》and the combo with Rafion are too famous.
Combo with Hell Tempest is also effective because it can receive a large amount of battles damage. The same damage goes to the opponent, and another disadvantage is that it self-destructs, so the situation doesn't get worse than using it normally.
On the contrary, Kaiju's compatibility is already good, but if you send Gameciel as a hindrance and attack with Jizkiel equipped with a fragile blade, it will meet the conditions of Hell Tempest and become an ideal place.
It is also highly compatible with cards that reduce battle damage to yourself to 0, such as Secure Gardner. Especially bad is "Kuriphoton", if you set the damage of this turn to 0 and use Recruiter to kill yourself, that's it. Of course, super hippo and tellus that can produce low ATK tokens are also good.
All of them are terrible combos that can decide the game, but I give him 9 points because his Equip Spell doesn't work alone and he needs to go through combat. Personally, I feel that 10 is not enough.
Addendum: Since it can receive a large amount of battle damage, it seems to be compatible with Sunavalon. If you don't die from that damage, you will heal yourself and only your opponent will get a lot of damage, and he will come out with Sunvine.

Cards that go great with the Timelord
It's especially compatible with Raphion, and by equipping it on a monster with 2000 or more ATK on the opponent's field and hitting it with this guy, all his LP will disappear.

It's a general purpose card, but it's also a one-turn kill card. Those are the main ones.
Equip this card to an opponent's monster with his ATK over 2000, and attack with 《Raphion, the Timelord》to achieve 4000 damage + 4000 damage and one kill.
Above all, this combo has a high success rate, and this card can be played with 《Hidden Armory》and 《Armory Call》, and Rafion can be played with 《Time Maiden》, which is easy to recruit, so you can easily get them together. Even if your opponent doesn't have enough attack, you can aim for a kill in that turn if you halve your LP with Michion first.
After that, whether or not the effect that targets the opponent's monster will work, and whether the ATK increase effect will work or not. Even if you don't equip a monster that has any resistance, you can just equip it to the monster next to it, so the difficulty is not high.

His Equip Spell dramatically increases the value of monsters that inflict battles damage such as 《Amazoness Swords Woman》.
Normally, even if it is 2000 up, it has a heavy disadvantage and is below average performance, but since the damage received by each other is treated as battles damage, it is now possible to effectively double the damage with a card that transfers the damage received to the opponent as it is.
In particular, he can share the support with Rinaldo, who supports Equip Spell, and is a major player with Amazoness Swords Woman, which can be used alone, and is compatible with the Timelord, who also has Rafion.
It's a basic combo premise, so it won't be used properly, but I think it's a definite advantage that it excels in one trick as a mine frame.

A card like the final type of suspicion that has not been played in the contest test. If you send Jizukil, put this on, take out Secure Gardner, and attack with a small one with a RBI of 1600 or less, it's just crazy to complete one kill...
Since it's an equipment card, it's easy to search for, and it has a terrifyingly wide range of abuse, so it's expected to be banned sooner or later.

A double-edged sword seems fragile. 2000 up is a moderate increase rate, but since it is possible to deploy a large amount these days, even with 3 units, United We Stand will increase the RBI by 2400. When you think about it, the main points are that they receive battles damage from each other. As already said, I still want to combo with 《Amazoness Swords Woman》. If there is a monster with his high ATK on the opponent's field, it is possible to equip that monster with 《Double-Edged Sword》and attack. If he is Blue-Eyed, 5000-1500 = 2x 3500, 7000 damage goes flying to the opponent. It's also fun to equip it directly when your opponent declares an attack with Armory Call.

A card for aiming for one kill by comboing with amateur swords.
Considering such usage, this score.

ATK is increased by 2000, and the damage that occurs in battle literally bounces back, so the disadvantage is painful. If you take advantage of the monster effect, you can aim for 7000 battles damage instead of the opponent's direct attack of "Amazoness Swords Woman".

Although it is almost unconditionally a large ATK increase, there is a severe disadvantage that it receives damage from each other and self-destructs after a certain amount of damage.
As far as equipping it on your own monsters, it's just one of the ways to break through imaginary enemies that you want to break through by destroying them in battle. Gladiator Beast class is barely adopted... maybe?
The best feature is that "both sides take damage no matter what", so you can push it to your opponent and force damage to your opponent, or adjust the damage and use it as a variant of his Junk Attack with Rikuru Special Attack Deck.
《Swords at Dawn》becomes a pseudo 《Heroic Retribution Sword》.
It seems that unity can be differentiated by making use of that area.

It raises ATK by 2000 points, but it is a fragile card with double-edged blades, such as the battle damage given by the equipped monster will affect each other, and it will break if it receives more than 2000 damage.
The amount of increase in ATK is exceptional, but his raised ATK is a scary card that turns his fangs against himself. I thought about various things, but it's hard to come up with a useful combo. Combos with cards that inflict battle damage to the opponent, such as Amazoness Swords Woman, are pending ruling.
After all, 《United We Stand》and 《Mage Power》can be upgraded to a level comparable to this card if you put in a bit of effort.

It's attractive to increase RBI by 2000 without cost with one card, but it breaks if you deal too much damage, and if you take battles damage on each other, it's a disadvantage.
Depending on the case, you can also think of how to use it to equip your opponent and attack them with a suicide attack to finish them off.
Benkei and Sagittarius, who aim for one-kill with Equip Spell, do not have good compatibility with each other because they take a lot of damage and even self-destruct on their own.
