renounce the guilds -- good in a multi-color cube
blood scrivener -- this guy may be a staple!
renegade krasis -- green needs more beef at cmc3, as without an extra color in there it's mainly utility and value dudes there. i'm gonna try it.
exava, rakdos blood witch -- may suffer from cmc=4 and the same issue as krasis, viz. not enough counters, but seems strong to me.
legion’s initiative -- probably doesn't justify its awkward cost and marginal effect especially in a cube without many sweepers
mirko vosk, mind drinker -- ends the game in a hurry, not sure if it's the kind of effect i want though.
progenitor mimic -- 6-mana simic repeatable clone is already filled by spitting image, and this card is not from eventide, but i like it a lot. clones are fun in cube.
ral zarek -- worth a try, especially if your izzet section is light (like mine)
savageborn hydra -- an heir to the surprisingly good wrecking ogre, being double-strike and too inefficient for constructed but maybe it'll find a home here. gruul doesn't lack for sweet options, though, and i'm not sure this guy is good enough.
sire of insanity -- worth testing, i love this design.
tajic, blade of the legion -- not my favorite (medic makes all! your guys indestructible) but we'll see
varolz, the scar-striped -- graveyard theme!!
voice of resurgence -- very hard to evaluate, so must try it.
zhur-taa ancient -- with wake being mostly unplayable i'd be hesitant to slam him in but who knows.
far // away -- probably just bad jilt, which i don't see in many lists these days, but w/e
flesh // blood -- incidental graveyard hate plus recursion is nice, probably not good enough though
your thoughts here!
