Punishing someone at the table, possibly someone you cant attack profitably through a pillowfort or doubling damage on someone you can easily swang at is pretty powerful
Just stick Poison Barb to your Active Pokmon and let Nihilego chill on the Bench, letting More Poison take effect
The main difference here is that you can buff the tokens with life
Any red deck can make room for a copy there aren't many games where you wont have a good opportunity to fire this off, efficiently answering a creature or artifact
Casual players have more flexibility, though the language barrier can make Japanese cards challenging without translation references
Needless to say, seeing a Pokmon that looks like its wearing a KaibaCorp mas production disk (oops, I mean, I have no idea which version) seems a bit silly
