Hey bro, was checking through this one and thought you could possibly update it for dom. Some thoughts:
Cabal Paladin would be awesome in this deck, very punishing. You could set up a damned if you do, damned if you don't setup where you have
Bontu's Monument out or
Cabal Paladin or something similar and then have it so that they take damage on cast, and then they take damage if it goes into the bin via
Pia's revolution.
Walking Ballista would be awesome here too, as you could dump mana into it, ping for a bit of damage, it dies and then triggers
Pia's Revolution for more damage. Or you could cast it for 0 mana, triggering revolution straight away. Might be able to work in Teshar and some ornithopters too for creature cast damage.
