With Volcano hellion it's infinite!
The problem is that i after casting fluctuaror they are useless cards in my library.Also i play just 9 sources for enlightened tutor. Just 1 or 2 gambles woud be an option because of the spirit guides.
Sure it's not always turn 1 but there aren't decks with more than 80% chance of turn 1 win.I think the turn 1 win is around 20% if the opponent does nothing.If i resolve flucator it's 95 % to win the game in the same turn.
