Rouse⁣ - Mercadian Masques⁣ (Common)⁣ [157]

Rouse allows you to temporarily boost a creature's power by +2/+0 for just the cost of 2 life if you control a Swamp, making it a flexible option in black decks. This instant can help you surprise opponents during combat or push through extra damage when needed. However, the life payment may be a concern in longer games, so it's best suited for aggressive strategies.
