Humno Pirif, Mirror Master

When Humno Pirif enters the battlefield, you
may have it enter with X +1/+1 counters or
create X non-legendary token copies of this
creature.
Instant & sorceries cost {1} less. When you
cast your second spell each turn give all token
creatures you control a +1/+1 counter.
If this creature would leave the battlefield,
you may sacrifice a token creature instead.
