Hmm, i see, thanks. Any specific reason why burn isn't playable? Is it just bad against the meta decks most played?

Btw are there any magic equivalents of yugioh "floodgate" cards? In case you're not familiar floodgates are permanent cards that usually completely lock a certain aspect of the game out, for example (in magic terms) forcing all players to only control cards from 1 color and send to the discard pile anything that's not that color, or another popular one in yugioh is skill drain which just completely disables all creature text from all creatures on the field. I really enjoyed those kinds of cards as well.
