Terra, Magical Adept // Esper Terra

Cards

Cast
Dominion Saboteur by paying its mana cost, choosing to have it enter the battlefield as a copy of
Esper Terra that isn't legendary. This will cause it to enter the battlefield with a lore counter as it will be a Saga.
Dominion Saboteur's first chapter ability triggers, creating a token copy of
Dominion Saboteur with haste, which will enter as a copy of
Esper Terra with haste that isn't legendary and with one to four lore counters on it.
The
Dominion Saboteur token's chapter abilities will trigger according to how many lore counters were placed on it.
Resolve the first
Dominion Saboteur trigger, creating a token copy of
Dominion Saboteur with haste, which will enter as a copy of
Esper Terra with haste that isn't legendary and with one to four lore counters on it.
Repeat from step 3.

This combo has been estimated to be Powerful (Bracket 3+).
