I kind of agree with you, and kind of don't-
archfiend of ifnir's ability is incredible, almost a nonstop board wipe if my opponent is trying to play creatures, but as many games I've had with this list essentially end with
living end, it IS striking me as more of a sideboard card. All the same I think I'd prefer to sub in architect of will rather than
deadshot minotaur, so there's no risk of killing archfiend of ifner myself when he IS out :3
I'm also dropping the count of
igneous pouncer and
valley rannet to 2 each, this has been amazingly consistent mana wise
I've played dozens of games with this list on untap.in in the last couple days, and I've gotten at minimum 2/3 wins EVERY single time with the exception of one loss to a janky combo deck :3
definitely leaning towards purchasing this list paper ^^
