Solitary Sword of Poison →Used Deck

Or the Sword of Solitude.
When the equipped monster battles an opponent's monster, it has a powerful effect that doubles his original ATK and DEF, but has the disadvantage of self-destructing when a monster other than the equipped monster is on his field.
As an Equip Spell, it's a pretty powerful correction, especially if you put it on a monster that originally had a high ATK and strong resistance to effects. However, on the contrary, since it only doubles, it has little effect on cards with low ATK.
Also, since it is limited to when fighting monsters and does not exert its effect when attacking directly, the speed of attacking is slowed down.
The ideal equipment to equip is a large monster that can activate a powerful effect when a monster is destroyed by battle. The first thing that came to my mind was Inferno Wing. !

In other words, if you equip it to Chaos MAX, it will kill all monsters with 4000 or less DEF.

Even though he is forced to be a loner, his ATK is doubled, so he is strong in battles with monsters.
I want to use it in combination with a monster that can attack continuously.
Since it doesn't double when it's a direct attack, it looks like it's going to be a big success with one kill, but it's slightly difficult to use.

Mutual compatibility of gigantism
Although his original ATK is twice as strong
However, it's fragile with Equip Spell, and it's a shame that it doesn't go up with direct attacks.

General-purpose version 《Cubic Wave》. That's what I said. However, this one does not lower his opponent's ATK like Wave, basically cannot search, self-destructs if a monster other than the equipped monster appears, and self-destructs even if your opponent generates a token. . A truly lonely and poisonous sword.
Basically, it can be used when you use all the monsters on your field and only have one trump card. Ultimate Hayabusa, Final Fortress Hayabusa, Supreme King Dragon and other trump cards with effect resistance, and Malefic, who is originally single and has a high RBI, can be overwhelmed by single combat. Hits damage close to . Sky Striker Ace, which fights alone, is also good, but it can't be maintained due to repeated link summons during deployments, so it's best to use it when you need it most. Since it is the original offense and defense that changes, if it is originally 0 or low, it will not be effective, so it is not suitable for avatars and wolves to equip it. This card itself doesn't have resistance, but since it's a basic trump level monster you equip it with, it doesn't seem like you need to worry too much about it, but the drawback is that it will rot in your hand until you get a trump card. Also note that direct attacks don't double.
