How it works
At the beginning of your combat phase, Mirage Phalanx and Ardent Elementalist each trigger, creating a token copy of Ardent Elementalist and Mirage Phalanx with haste and without soulbond.
When the token Ardent Elementalist enters the battlefield, it triggers, returning Savage Beating to your hand from your graveyard.
Declare Wildfire Eternal as an attacker.
When Wildfire Eternal is not blocked, it triggers, casting Savage Beating from your hand without paying its mana cost.
Resolve Savage Beating, causing you to untap all creatures you control and to get an additional combat phase after this one.
At the end of your combat phase, the Mirage Phalanx and Ardent Elementalist tokens trigger, exiling themselves.
