Thought Process

Choose target player who hasn't cast a spell
named Thought Process this turn. You control
that player during that player's next turn.
If you cast Thought Process from your hand,
each player may bid life. You start the bidding
with a bid of any number. In turn order, each
player may top the high bid. The bidding ends
if the high bid stands. The high bidder copies
this spell and may choose new targets for the
copies.
