Oh yeah. Nobody packs any general purpose removal except O-rings, but they typically use them up on crits before I drop my Crucibles. Usually by turn 4, I start slamming too hard for them to come back.

The mana base...wow. It rocks hard. I have never been manascrewed out of a Horde or Reaper on 5 lands. Thank you Reflecting Pool/Vivid!

Scarblade + Crib Swap/Inversion combo...that rocks hard.

Another fun combo? Toss a single Mothdust Changeling at a Woolly Thoctar, then when he blocks and it dies, tap and RFG to kill. Great for taking down a game winner at turn 3.

Sprouting Thrinax? Pyroclasms. Ajani Vengeant? O-rings. Or Flame Javelins. If they're utterly devoid of removal, I always like the Familiar's Ruse/Reaper combo.

This seems cool, although I'm not entirely fond of an aggro deck relying on Vivid Lands and general pumps. But if it's working, keep at it.

Its more of a late-game slammer, the early game is for control. I won turn 6 last time with a Colossus and 2 Shapesharers. The guy had the misfortune of being at 11 life with all crits either tapped or killed.
