I run "Varolz, the Scar-Striped" a 2/2 for one green, one black, and one generic you get a 2/2 with scavenge. This deck was just given to me by a guy with a bunch of janky cards that didn't work well with it at my LGS. I've been tooling it for several months now and it's getting tighter and tighter. Currently I'm happy the way it performs but will get probably 10 cards to sub-out depending on who I play. Also no "Doubling Season" for me . . . just too expensive. This deck was given to me and I just bought a bunch of cards to tune . . . that's as budget as it gets.
