Valamir, Trickster Trader

Shroud, Indestructible
At the beginning of your upkeep, target
opponent gains control of another permanent
you control. Then, gain control of target
permanent from each opponent controlling 3 or
more permanents owned by you.
At the beginning of your post-combat main
phase, gain {b/r} for each of your permanent
you control but don't own.
If this is the only permanent you control, you
lose the game.
