Circu's Bar

Circu's Bar enters the battlefield tapped,
unless a creature you control has flying.
{t}: Add {b} or {r} to your mana pool.
{t}, {b/r}{b/r}: target creature you control has
flying until end of turn.
"It's common knowledge Circu's is a front,
what for is a different story."
- Inchoku, Goddess Imbodied
