Mystic Remora Art, Variants, and Market Value: from Ice Age to Modern Foils
Q1: Does Mystic Remora trigger if an opponent casts their commander?
Only if that commander is a noncreature card, such as a planeswalker or an enchantment commander. If the commander is a legendary creature, Mystic Remora will not trigger.
Q2: Can I draw cards off Mystic Remora triggers before I pay the cumulative upkeep cost on my turn?
Cumulative upkeep occurs during your upkeep step, which happens right after you untap. Because opponents rarely cast spells during your untap step, you typically pay or sacrifice the Remora before any new spells are cast on your turn. However, if an opponent casts an instant in response to your cumulative upkeep trigger, you will get a draw trigger before you decide whether to pay the upkeep cost.
Q3: Why do players call Mystic Remora "The Fish"?
The card's name refers to the remora, a family of suckerfish known for attaching themselves to sharks and whales. Players affectionately call it "The Fish" or "Fish" based on the creature type depicted in Ken Meyer Jr.'s original Ice Age artwork, despite the card technically being an enchantment rather than a creature spell.
