I love the deck anyway but the upvote was because of my favorite funny pet card I love using and that is Permeating Mass. However I did some looking around so suggestions/ideas are clockspinning, nesting grounds, power conduit, quarry hauler, and Chisei, Heart of Oceans. Not that these have or haven't crossed your radar just suggestions
Thank you for your suggestions.
Power Conduit definitely slipped by me. I'll have to keep that one in mind as I play test.
I did think about the other ones. My strategy is to draw cards and play a bunch of 1 mana spells to remove counters. Then my higher CMC cards are to pillowfort/stax and get my 12/12 through combat. So
Quarry Hauler and Chisei didn't make the cut at CMC 4. I really considered
Clockspinning; but I didn't see me using the buyback option very often. Cut it in favor of draw spells. And unfortunately,
Nesting Grounds is currently in my Kathril deck. Otherwise it would be there.
