There are a couple of more tame effects (i.e., Crystal Fragments) that are technically DFCs though
Neyith of the Dire Hunt is a great commander, but it will do good work in this deck, since you get to draw a card when Zangief gets blocked, and if the path is clear, you can double Zangiefs power with the beginning of combat ability
Some perfect fit sleeves actually tend to run a bit small so theyll hug your cards a little too closely and warp them over time
The deck produces tons of mana you can feed into X spells like Torment of Hailfire and Genesis Wave, or you can take the classic route of jamming Eldrazi titans
Gilgamesh, Weapon Collectors second trigger isnt that impressive, but its good enough without it
I dont want to call them not fun, since they usually are fun
