Invasion of Muraganda // Primordial Plasm

(As a Siege enters, choose an opponent to protect it. You and others can attack it. When it's defeated, exile it, then cast it transformed.)

When this Siege enters, put a +1/+1 counter on target creature you control. Then that creature fights up to one target creature you don't control.

At the beginning of combat on your turn, another target creature gets +2/+2 and loses all abilities until end of turn.
