ROFL! Oh my, that's amazing. Misere magic! And probably fair, for that cost (although wizards might well be safe and make it cost 10 just in case) :)

Unfortunate for the player playing pacts, or burn spells, or life-paying cards, but it'll almost certainly be funny whatever happens :)

Only plausible now that manaburn is gone, I guess. Even then though, the game's going to be pretty un-fun after the reset.

Your opponent would always do: "My turn? Nothing to untap, no upkeep, draw, end turn, discard. your turn" Unless they wanted to get to 8 to cast this on someone else...

So you're relying on having a larger deck (fun 60 null turns to look forward to), or the opponent having a lose condition in theirs.

Heh. So my entire deck consists of ramp, tutors and Reset, with no way to win, or even stop my opponent. When the game does Reset, I need to win before my opponent ramps, tutors, then Resets. Wait. That doesn't make any sense...

It probably should cost about 10, however. 8 isn't hard to get to if that's the whole goal of the deck. I'm guessing that I'd have about a 65% chance of getting to 8 mana by turn 4 in many environments.
