Mate, i think you should add some more lifegain outlets , ass you want to use the full potential of Krrik to cast for life rather than for mana cost. Also i think you should add more 0, 1 ,2 cost mana artifacts so you can cast Krrik ass son as posible. You can check out my Krrik deck , maybe you can get some idea out of it :) Never the less, keep up the good work!

Demonic Embrace is great for not only giving K'rrik more power to gain more life, but also giving him evasion so you'll always be able to attack. It's reusable, too.

Unless i missed it, a sac outlet would be nice. I’ve won plenty of games with Gray and Phyrexian Reclamation by sacrificing to a visera seer and replaying gray. This deck is awesome!

KingLonsur TY

The deck has been a blast to play. I need more tutors though.

I never thought about a sac outlet.

Spawning Pit and Phyrexian Altar Would do amazing in this

dlxhaz Idk what to cut for the alter though

Karn's Bastion might be a good card for you so you can Proliferate your commander, and poison counters and ult your plainswalkers faster,

Jimmy3671 that's an interesting card to put in, but I don't think it would be very effective. The deck doesn't have a lot of infect outside of Tainted Strike
