Crux, The Jank Lord

Crux, The Jank Lord's power and toughness are
equal to the number of Jank permanents you
control.
Other Jank creatures you control gain +2/+2.
Whenever an opponent casts a noncreature spell,
you may sacrifice a Jank creature. If you do,
choose one:
•Counter that spell,
•Any target gains shroud until end of turn,
•Proliferate.
