Brutal Cathar // Moonrage Brute

Sep 24, 2021 · Brutal Cathar's ability creates two one-shot effects: one that exiles the creature when the ability resolves, and another that returns the exiled card to the battlefield immediately after Brutal Cathar (or Moonrage Brute) leaves the battlefield.

Sep 24, 2021 · A transforming permanent doesn't leave the battlefield as it transforms. If Brutal Cathar transforms into Moonrage Brute, the exiled cards remain exiled. If it transforms with its triggered ability on the stack, that ability will still exile the target creature.

Sep 24, 2021 · If it is night, and the active player of the previous turn cast two or more spells during their turn, it becomes day.

Sep 24, 2021 · Moonrage Brute leaving the battlefield will also cause the exiled card to return to the battlefield.

Sep 24, 2021 · If you cast a spell with daybound during night, that spell will be front face up (that is, daybound face up) on the stack. However, it will enter the battlefield with its back face up (that is, with its nightbound face up). It won't enter with its daybound face up and then transform.

Sep 24, 2021 · In a multiplayer game, if Brutal Cathar's owner leaves the game, the exiled card will return to the battlefield. Because the one-shot effect that returns the card isn't an ability that goes on the stack, it won't cease to exist along with the leaving player's spells and abilities on the stack.

Sep 24, 2021 · If it is day, and the active player of the previous turn cast no spells during their turn, it becomes night.

Sep 24, 2021 · Permanents with daybound and nightbound can't transform via any means other than their daybound and nightbound abilities. Notably, older cards such as Moonmist that instruct a player to transform permanents don't affect permanents with daybound or nightbound.

Sep 24, 2021 · Auras attached to the exiled creature will be put into their owners' graveyards. Equipment attached to the exiled creature will become unattached and remain on the battlefield. Any counters on the exiled creature will cease to exist.

Sep 24, 2021 · If Brutal Cathar leaves the battlefield before its enters-the-battlefield/transforms-into ability resolves, the target creature won't be exiled.
