After playing with the deck a bit on magic arena in the new format, I can report that the deck has been performing well. I was able to climb to platinum relatively quickly this far and plan to continue trying to climb.
Embercleave is a really strong card and downright wins games as early as turn 4. In this early unrefined meta, we can really take advantage of the slower midrange or control decks that fumble around early too much.
One popular play pattern I see in control or late midrange match ups is Anax, Hardened in the Forge turn 3 while on the play into an opponent's turn 4 sweeper. It's usually punished by a turn 4 Torbran, thane of redfell of our own and a bunch of Satyr tokens.
Until the meta settles, I am content with the list for now.
One argument I run into is why not just play Gruul aggro. I think both decks are potent aggro decks and have an embercleave finisher. I prefer the all red version since we have no mana issues, can get extra value from Runaway Steamkin pretty quickly, and use Anax, Hardened in the Forge optimally. Edgewall Innkeeperl provides good value in gruul aggro adventure lists, but we have Ox of Agonas to provide some card advantage in a different way late game.
