Eenteresting. Does attacker get first refusal? What if there are multiple attacking or defending players? What happens if both sides pay?

My thinking was that the actual text (not reminder) is somewhere along the lines of:

> ": Remove ~ from combat. It blocks target attacking creature (if able?). Activate this ability only during the declare blockers step."

> ": Remove from ~ combat. It attacks the defending player if able? Activate this ability only during the declare attackers step."

Hmmm, this would mean that the blocker would have the last say since that step comes afterwards. Eh, maybe the mechanic's implementation could be envisioned in some other way.

Also, there would have to be rules about who divides the combat damage between blocking creatures and such.

EDIT:

Perhaps you could try removing the option for other players to "hire" them and have the ability just be ": Gain control of ~ UEOT."

Ie.

For hire (This creature isn't controlled by any player. It has ": This creature's owner gains control it of until end of turn.")
