I like this one a lot better save for 1 thing...wording. This way everytime it attacks it banishes a monster and deals damage, that's cool. Problem lies in the fact that when your opponent's monsters change upon attack declaration you get to retarget your attack...so you could effectively banish a full field for tons of damage. Not sure if that's coincidence or intentional, but I thought I'd mention it.

So maybe say "once per turn/once per attack"?
