Harley Quinn

Vilain, Reach — Partner with Joker, Murderous Trickster
While Harley Quinn is on the battlefield, if
Joker, Murderous Trickster would be sent to the graveyard, instead exile Harley Quinn with 3 jail counters (at the beginning of your upkeep, remove
one jail counter. When the last jail counter has been
removed, put Harley Quinn back onto the battlefield.)
