Wins on turn 3-4. Scoops to pyroclasm. Incredibly fun to play.

Seton's ability is an activated one: this means that all your druids are basically hasty and give back mana. You generally keep a hand that can cast Seton AND has a way to draw cards. All this deck needs is gas and you need to feed it cards to keep playing.

There's a couple infinite combos in it, but the thing is they're only there because the cards just work so well outside of being combo pieces.
