Xeno'jiiva, the Sapphire Star

Mutate {4}
Converge — Xeno'jiiva enters the battlefield with
a +1/+1 counter on it for each color of mana that
was spent to cast it.
Whenever this creature mutates, choose a kind of
counter at random that Xeno'jiiva doesn't have
on it from among flying, first strike, deathtouch,
hexproof, lifelink, menace, or vigilance. Put a
counter of that kind on Xeno'jiiva.
