Bioluminary (UNF 324)

Creature — Merfolk Performer • Mana cost: {2}{U} • Unfinity • Uncommon

Whenever Bioluminary deals combat damage to a player, you get {TK}{TK}, then you may put a sticker on a nonland permanent you own.

The Gargantikari astroserpent hated the taste of merfolk, but the audience didn't need to know that.
