Yeah, I think ramp is a very dispiriting thing. Artifact as a whole sometimes feels like Valve and Garfield haven't learned from the current generation of board games - that removing someone else's ability to play entirely (through Annihilation), or being unable to even push for a draw (through ramp+ToT), makes the game one-sided and not-fun for one of the players. I've sometimes surrendered right after the opponent has played ToT, because whilst I may be able draw, or even win, it just isn't fun. The same with board-wipes - Annihilation? Nah mate, you can have this game, I'll play against some other deck where it doesn't feel like I'm just wasting my time.
