I'm thinking something like this:
Ok, so this is along the lines of what I am thinking a semi viable (tribal style) zombie aggro deck looks like with the new mythic 2 drop gem that zombies didn't have before. Relentless Dead seems to be good enough to hold it down and improve on a tribal zombie deck, maybe enough so to make it able to win a local legacy event at least, lol. I am a little confused making this deck as there is so much competition for card slot's but I think it could work.You could go heavy 1 drop and do Carnophage maybe even the 1 drop enchantment (name) even that makes the 2/2 zombie that you sacrifice if you control no zombies. I want to have a decent curve and utilize going wide. Maybe Rotlung Reanimator You've got Withered Wretch for the sideboard which is kinda nice I suppose (haven't even thought of it yet i'll get there in time). Maybe more removal? Go for the Throught or something like Dead Drop, but I kinda like the random swings of Thoughtsieze in to Hymn to tourach, that variance can just win with hymn. Maybe more discard, a couple Inquisition? Tell me what you think. Tidehollow Skuller??
