Brineborn Cutthroat (M20)

Creature — Merfolk Pirate

Flash (You may cast this spell any time you could cast an instant.) Whenever you cast a spell during an opponent's turn, put a +1/+1 counter on this creature.

Reliable tempo threat for blue interactive decks. Brineborn Cutthroat rewards the instants and flash spells that control and tempo strategies are already running, turning your interaction into board presence. Flash lets you deploy it defensively or hold up mana for interaction, and it grows quickly in any deck built around instant-speed plays. A strong inclusion in Modern and Pioneer tempo shells, and a solid role-player in Commander's blue tempo and control strategies.
