Falin Curious Cleric

{2}{w}, Sacrifice Falin: phase out any number of creatures you control. (While they're phased
out, they're treated as though they don't exist. Each one phases in before its controller untaps during their next untap step.)

When Falin dies, if a creature named Red Dragon is in your graveyard you may exile Falin and Red Dragon, and meld them into Chimera Falin Rampaging Beauty.
