I see. Well, as long as you have a good reason.

Hah! Too many Chiefs and not enough Indians. Classic.

Have you considered Sidisi, Undead Vizier? It would work very well here. Also Ruthless Deathfang so when you exploit something your opponents have to sac a creature.

Den Protector and Deathmist Raptor if you can find and pay for them?

I have thought about those two, their synergy doesn't justify the cost sadly, I also have enough ways to cycle my yard with gravepurge if i need it. Thanks for the suggestion though!!

How about Strength from the Fallen? Or Nighthowler? Or new Graveblade Marauder?

I intend to add graveblade when he comes out. I don't run enough enchantment to add strength from the fallen. I would like to add night howler but I dont know what I would drop. Any ideas?

a couple of suggestions from running a similar deck, Nemesis of Mortals can totally kill. Play him for 2 and monstrous him for the same. he makes a huge threat for very little mana.

Corpseweft could mayyybe see some play here. I always liked it a bit better than Gravepurge.

Maybe try Sudden Reclamation instead of Scout the Borders, its one more mana but you can grab any creature in your grave and any land. Which I know isn't as important in this deck, but if you missed one of the mega-powered Sidisi, Brood Tyrant you gunna wanna try to get them back. Nyx Weaver also pairs well with a Sidisi strategy, is good for flyers, and gives recursion of any card.

Might I also recommend Minister of Pain against mono-red decks.
