For enchantment woes, all I can think of are more sweepers like Ratchet Bomb , Oblivion Stone , Worldslayer , and Bearer of the Heavens .

There's also the cumbersome Lux Cannon , Spine of Ish Sah , and Argentum Armor .

You may consider resorting to anti-white cards like Anarchy , Omen of Fire , and Dystopia .

Thanks for the suggestions! If Bearer of the Heavens had a reasonable mana cost at all, I'd seriously consider it in here, as I can sacrifice it to one of my many sac outlets and get my creatures back at end step, effectively winning me the game. I'm also giving a good bit of thought to Lux Cannon and Oblivion Stone . Currently my problem with sweepers is how they interfere with my artifact mana, but the Stone seems like a really solid addition.

Nicol Bolas, Planeswalker is often a good choice in any grixis colored deck.

The absolute best card for dealing with enchantments for me is Aura Thief

Doesn't deal with rest in peace at first, but you should have ways to sac permanents in that deck right? I run Claws of Gix + Trinket Mage . Works wonders. I also run Zealous Conscripts and Nicol Bolas, Planeswalker . They both help deal with pesky enchants.

Aura Thief is a decent enough card but from testing it i found the average boarstate to be lacking in permanents. I had been considering Claws of Gix but at the time it seemed inferior to other sac outlets due to the activation cost and myself only having one "gain control" effect in the deck. Ive also been having fewer problems with hate enchantments since i worked Chaos Warp and bounce spells into the main. That being said, i like the suggestions and that package seems like a clever solution.

I like Phyrexian Purge in my Marchessa deck and Dracoplasm is pretty fun.

Keiga, the Tide Star could be another "gain control" creature if you were looking for more.

Insurrection + Any sac engine. Gain control of all creatures, attack the person with the highest life total, sac the creatures, get control of them forever.
