Wildfire Eternal | Savage Beating | Mirage Phalanx

(and one other card)

At the beginning of your combat phase,
Mirage Phalanx and
Archaeomancer each trigger, creating a token copy of
Archaeomancer and
Mirage Phalanx with haste and without soulbond.
When the token
Archaeomancer 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
Archaeomancer tokens trigger, exiling themselves.
Repeat each combat phase.
