Probably good for 2 blocks and 6 attack, which is pretty reasonable for a 4-cost ally. The response seems pretty niche, especially in single player play. I can't come up with a whole lot of reasons why playing a Hero action event in the villain phase is superior to just waiting for your turn, though it might let you take out a minion before it activates.
Since archangel's ability is once per phase, you can trigger it again when playing an event during the villain phase

In a 3 (or more) player game, you could defend Player 1 with your Hero, defend Player 2 with Warpath and activate a event who readies your Hero to defend another Player.
