Horrible Lock Placement

Whenever a player taps an Artifact or Token they control, you may pay {2}. If you do, that player flips a coin. If that player loses the flip, exile that Artifact or Token. If that player wins the flip, you must exile an Artifact or Token you control of their choosing instead.

At the beginning of your upkeep, if there are no other Artifacts or Tokens on the battlefield, sacrifice Horrible Lock Placement.

Damn.
