Castien Crearis, Elven Tyrant

Castien Crearis cannot attack or block if you
control another Elf.
{b}, Sacrifice another Elf you control: That
creature deals damage equal to its power to target creature. Put two manipulate counters on Castien Crearis.
Remove ten manipulate counters: Gain control of
up to four target elves.
A master of manipulation, Castien was the worst
tyrant The Towering Forest has ever known.
