During the End Phase, if this card was Normal or Special Summoned this turn: You can target 1 Spell Card in your Graveyard; add it to your hand. You can only use this effect of "Dark Magician of Chaos" once per turn. If this card destroys an opponent's monster by battle, after damage calculation: Banish that opponent's monster. If this face-up card would leave the field, banish it instead.
Use Diffusion Wave-Motion so that Dark Magician of Chaos can attack every monster your opponent controls, removing them from play and negating their effects. You can then retrieve Diffusion Wave-Motion if Dark Magician of Chaos was summoned during that turn.
broken? there's fuk loads of other broken cards in this game
Funny and consistent.
With 3 Draining Shields and with this skill it's reaaaally easy to get whatever the hell you want in the draw phase. If the opponent decides not to attack, then you will have more time to setup / get more supports / even tribute summon.
I'm having a really good win ratio with this against really good decks in KoG. And of course the win rate will rise even more after CA's nerf.
