Nika Felis, Feline Shadow

Protection from White & Blue
When Nika Felis enters the battlefield create a
copy of another target creature you control
except its a 1/1 green Cat. The copy is not
legendary.
As long as you control a Cat creature Nika
Felis can't be blocked.
She bears the skull of one feline adversary on her
head as a warning to others that she has capabilities
as powerful - and as dangerous.
