Correct on all points, especially about the Trumpet Blast. I was actually pondering that the other day.Purph was aweful for the tourney since I was racing every round and had to board it out in the majority of the games, but in a more open field, he's awesome.
His pump ability saves me from boarding trash like trumpets blast(may still board it cause...scrump).
Ashcloud is dope as fuck. There's a different deck I could build that's bigger, but at that point, you have to start asking if devotion red is better. You don't have to though because Phoenix is fine in all non-combo archetypes and matchups.
Your devotion statement is pretty on-point. I asked myself the same question when I first posted
the deck.
