I've considered a few names for this deck.
Wumpus! There it is!
Wumpus, wumpus, wumpus
Things that go Wump in the night
My lovely lady Wump
A priest and a rabbi walk WUMPUS!!!!
maybe add in card:Garruk's Horde so you can play them off the top in case they keep sacing land.
Tried card:Garruk's Horde. It's not a bad idea, but my mana ramp doesn't get me to 7 very often and his ability is conditional. I think I'm better off using those two slots to force land destruction.
Strip Mine would be helpful against green aggro decks in case you need to buy time to bring the noise, bring the Wumpus.
Maybe more red instant kill to protect your strategie from aggros, But great deck.
Thanks. And, yes, it does fair poorly against low-curve decks. I think a playset of Lightning Bolt and some other cheap removal would be good for a sideboard.
