Choice of Unchoosing

Target player chooses a creature, however
you may have that player choose a different
creature as many times as you want, as long
as it has not been chosen already.
Enchanted creature becomes 0/1 and tapped.
It cannot attack, block, untap, or use abilities.
"I will give you the honor of choosing.
No, not that one. Nope. Pick again.
No. No. No. Ah, great choice!
Wait, why are you upset? I let YOU choose!"
