Conceited Shifter

Menace

At the beginning of combat on your turn, Conceited Shifter becomes a copy of target creature you control. If that creature is a Sith, Conceited Shifter gets +1/+1 and gains, "Whenever a copied creature dies, put a +1/+1 counter on this creature" until end of turn.

If Conceited Shifter has three or more counters on it, it gains shroud.
