And why is this so good, huh? It can still be deflagged, destroyed by Pulvys, or even stealed AND you can heal yourself with Shards, Miracles, Stone Skins, and such. You get over with them 6, and ZOINK! It's out of his gases. Rainbow decks can still easily counter this one.
And sorryz, I don't like air.
Okay, let's stop whining. xD I should be the one who will be quoted here after all, so let's type some good things about this card.
Upgraded Gas deck is cheaper, and if you get them fast... ulti-pwnage. It damages the creatures too, so that's good. Can get rid of Skeleton BYard swarms, Malicells and spammed Fireflys.
