So far I'm not adding any of the broken powerful stuff. I don't want the power crept ridiculous stuff like Ragavan but if I open one of the Incarnations I'll consider them.

Persist is a strong buff to reanimation at 2 mana. The non legend clause is enough to finally cut Belzenlok. Since there are still no other good options I'm going to finally give Grave Titan a chance. I've kept him out for the entire history of the cube for being powerful but I convinced myself to give him a shot. Frogkin Kidnapper lost it's luster now that Elite Spellbinder gives this effect on a real card.

Timeless Witness is very medium but it buffs Pod decks and more cards that want to be dumped into the graveyard for green are welcome.

Dragon's Rage Channeler and Blazing Rootwalla are nice synergy minded 1 drops for red.

I was never sold on Jwari Disruption so I'm cutting it before it even got in a draft. Too many force spikes effects and Lose Focus is really strong.

Timeless Dragon Is nice because I had Eternal Dragon in my cube at the beginning and it lets white in on the graveyard theme more.

Sword of Hearth and Home will have protection taken off just like the others.

The card that's a perfect fit for the new equipment theme in Boros is Barbed Spike Another ancestral blade is great because they are flexible that don't need any synergies to run.
