Celeborn, Master Transmuter

At the beginning of your upkeep, choose one --
- put a +1/+1 counter on another target creature.
- another target creature gains flying until
end of turn.
{t}: target spell, or permanent, becomes the color,
or colors, of your choice until end of turn.
"All things are mutable. We must simply learn how
to coax them."-- Celeborn, Master Transmuter
