I'm relatively certain that Ruhan is less playable than Lightning Angel (who is not be playable herself). Haste (to kill Jace), Flying (to kill Jace over his blockers), and Vigilance (so they can't profit from Bob/Snap on the backswing) are really good compared to more dumb power. Blocking for a turn against Blightsteel is nice too (Ruhan has to attack into BSC).
Test it out with 4x Ruhan, then test it with 4x Lightning Angel instead and it will be better. Then cut Lightning Angels for real cards like Vendilion Cliques and Jaces.
Ruhan has all the problems of being 'fair' without any of the benefits of being 'broken.' Stiflenaught is likely a better 'smash face with undercosted fatties' deck, even in a meta full of Mental Misstep.
Hah, that's ironic. I had 3x Lightning Angel and 3x Ruhan in the pool as I was tinkering with a first draft of this deck. Just like with Animar, though, my goal here is to see if Ruhan can be made to work specifically. I cut the Angels for Mox Monkey because the deck had no early game.
I'm brewing something else for Stiflenaught. Specifically, I'm trying to see if 4x Snapcaster / 4x Welder / 4x Stifle / 4x Dreadnaught could work. Caster doubles your stifles, welder doubles your naughts (and lets you sac one naught to another potentially).
Also, LOL on Wolly Razorback. I stand corrected - Ruhan is the only 7/7 for 4 that can attack out of the gates.
Chrome Mox is interesting. If I went back to having Lightning Angels in here too, that's a ton of multicolored cards to let me play Mox for value. Mind you, though, I was planning to run Stony Silence...
