Kawaki no Kaze / Harmful Wind
Continuous Trap
You can only use each effect of “Harmful Wind” once per turn. (1) If you gain Life Points: Target 1 monster your opponent controls; destroy it. (2) If you control an “Aroma” monster while your LP is at least 3000 higher than your opponent’s LP: You can pay the difference in LP; destroy any number of monsters your opponent controls whose combined ATK is less than or equal to the amount paid.
Poison of the Old Man and Draining Shield even more OP :D
