You can support it with a fair game, which Hemsley did somewhat, but it can be a proactive fair game, and I think attacking your opponent from multiple angles makes it a lot harder for them to prepare for (are they trying to stop your creatures/Stoneforge or your graveyard?) Another card that I think is way too good not to see play is Dakkon, Shadow Slayer
It's essentially a one-sided black board wipe
Again, a playset is needed here, please
I have made a list of the cards that I think do some of the most to enhance the game play in the cube by virtue of reducing luck based wins
These commanders are Yasova DragonclawYasova Dragonclaw (45% run Pod), Savra, Queen of the GolgariSavra, Queen of the Golgari (43%), Yisan, the Wanderer BardYisan, the Wanderer Bard (42%) and Mazirek, Kraul Death PriestMazirek, Kraul Death Priest (37%)
Some other outlaw payoffs include At Knifepoint to grant your assassins first strike, Back in Town as mass reanimation, and Double Down as a board-widener
