Ember Beasts are the most damaging tool in the deck’s arsenal, as they can dish out a high amount of damage for their cost. The problem is that they need the board state to be just right. Wildfire needs to trigger at least on one unit to make its cost worth it. If it triggers on more than one, then it can become devastating, especially on Spirit of the Phoenix turns. Born of Fire is the main way to increase this threat range, making Ember Mages, Ember Archers, and Holleas key for their use.
Trying to force the opponent’s movements into ending their turns with units one space away from a gate or an Ember unit is a big part of the Phoenix Elves’ play, which is a lot easier against heavy melee factions and where Ember Beasts shine.
Against factions with a stronger ranged game, Ember Beast effectiveness becomes harder to implement, and the Phoenix Elves rely more on Holleas, Fire Drake, and Ember Mages to make such match-ups work best for them.
