Oh and also the mainboard Crypt Incursion s. do you actually find yourself using that card? Surely it halts Consuming Aberration , or is it entirely as a last resort for you?

Crypt Incursion has saved me so many time and I don't care if it lowers my Consuming Aberration dmg because my focus is on milling my opponent.

Codex Shredder is also a card that has so many uses, vs scry, to return any card from your graveyard, to mill your opponent, to add more power to your Consuming Aberration , etc.

I'm not sure if I have enough Mill to have Codex Shredder be worth it, since i dont have a second Jace, Memory Adept or second Ashiok, Nightmare Weaver . Most of my games end with a 20,20 or more Consuming Aberration swinging in against an empty board, since I'm so heavy on removal, but theres 2 shredders in the deck now for play-testing. Also added 2 Crypt Incursion to the sideboard (I used to have 2 in the sideboard but took them out for some reason)

I like your deck. Its similar to mine except I'm running heavy on creatures and lighter on counter/destroy spells. Check it out? Budget Standard-Mill +1
