A skill with a lot of potential. However, since insect decks never found a way on the top tier list due to its lack of consistency, it is still recommended to use Parasite Infestation when trying to rank up.
I don't honestly understand why this skill isn't considered his best. Parasite infestation decks have never seemed to work well for me, where as the ability to permanently take away 800 atk from all opposing monsters over multiple turns . .is just nasty.
Agree with the use of worm bait to stack your side of the field to use this skill. Can combo in "mystic box" to give opponent a 0 atk monster.
