Emiel the Blessed

The blink-payoff commander Wizards has been refining for years, given a clean Unicorn frame. The activated ability is the engine: three mana to exile and return another creature you control (Emiel cannot blink itself), which means every enters-the-battlefield trigger in the deck becomes repeatable at instant speed, every aura or unwanted counter on the target is shed, and any troublesome enchantment attached to it is wiped clean. The returning creature comes back as a new object with summoning sickness, so this is a value loop and not a way to reanimate fresh attackers; the payoff lives in the triggers, not the combat step. That repeatability is also the card's defining identity: a blink with no per-turn cap is one of the most prominent infinite-mana enablers in the game, since any creature whose ETB produces four or more mana turns Emiel into an engine that generates unbounded mana and ETBs for a payoff to exploit. The hybrid trigger is the design discipline that keeps the fair side honest. A free +1/+1 counter on every ETB would be too much value bolted to a four-mana body that already prints its own engine; gating the counter behind a hybrid pip forces a real mana commitment per trigger, and the Unicorn bonus is the lineage tax that rewards building into the creature type. The closest functional ancestor is Brago, King Eternal, but where Brago blinks your whole board off a combat hit, Emiel sells single-target activations one at a time, which is exactly what makes the combo math so easy to assemble.
