The ones in the set are pretty good, but after looking into what we could choose from and talking to players at the CoolStuffInc in Tampa, Florida, I feel pretty confident that we've pinpointed the best five
Tangled Colony probably works best in multicolor decks where you have access to some direct damage spells, or at least spells that force creatures of your choice to fight.
Hired Claw does this, but its a lot easier to grow with +1/+1 counters
Maelstrom Wanderer, one of the best cascade commanders, provides pressure in spades thanks to the haste ability
If you don't, put it into its owner's graveyard
Depressurize can act both as a hard removal spell and combat trick, giving it flexibility that is newer to this sort of effect
