Doomed Reflection

Create a token which is a copy of target planeswalker you control. That token enters the battlefield with X loyalty counters on it, where X is the loyalty of the original planeswalker, halfed (rounded down). The legendary rules doesn't apply for the planeswalker and the token until the token leaves the battlefield. Exile the token at the end of the third turn after you have casted Doomed Reflection.
Better a soulless clone than a souled roach.
