Bottle Imp

Bottle Imp enters play with X cost counters on it. During their main phase, any player may pay any amount of mana less than the current number of cost counters and more than 0 to gain control of Bottle Imp, then reduce the number of cost counters to the amount paid. Cost counters may not be reduced by any other means. {T}: Bottle Imp recreates the activated ability of any permanent in the game, or the text effect of any Instant or Sorcery in the game. After each Stack resolves, untap Bottle Imp. If Bottle Imp would be destroyed, sacrificed, or exiled, it returns to the battlefield under its current controller’s control. The number of cost counters is unchanged. If a player would lose control of Bottle Imp other than by another player paying mana less than its current number of cost counters, return it to the current controller’s control. You may not lose the game as long as there is more than one opponent. If you control Bottle Imp at the end of the game, you lose. If this would result in a draw, the last player to fulfil a loss condition other than yourself instead wins.
