Rainbow Dash (SLD-1540) is a Legendary Creature — Pegasus from the Secret Lair Drop set. It grants flying and haste and has a mechanic that tracks “coolness,” giving incremental benefit when your flying or hasty creatures attack and a powerful Sonic Rainboom activated ability once a coolness threshold is reached. As a five-color–identity legendary with a tap ability that can produce one of each color mana and draw a card when charged, it serves as a potential finish or ramp piece in multi-color or casual decks.
