$&#* ^(&!!!

Revenge Hunter
DARK|*4|Fiend/Effect|1600/0

If this card is destroyed in battle and the card that destroyed this card as a result of battle is destroyed as a result of battle, Special Summon this card to your side of the field and increase its ATK by 1000. When this card's ATK increases or decreases, the result becomes this card's new original ATK.

[Valkyrie Lupia Blitzer]

Overcharged Anger Burst is underpowered.

$&#* ^(&!!! is pretty awesome, but it should be a Counter Trap.

Revenge Hunter is interesting, but not by much.
