I like a lot of pyrewild shaman in how it signals that red needs to be aggressive. It can also recur itself, which is nice. However, I also noticed that red does not have as many instant and sorcery cards that it should have. I think in most sets, it is number 4 in terms of creatures. My cube does not really reflect that. And while that's fine, it does hurt that Izzet is supposed to be spell slinging here. So this is the same P/T combat trick, it just isn't a creature. And instead of getting itself back, it replaces itself. Also, it still signals to attack since it focuses on power, but this gets to be a little more flexible.
