Risen Chitin-Brute

Endure {u/r}{u/r} (whenever this creature becomes the
target of a spell or ability, you may pay {u/r}{u/r}. If you
do, return it to its owner's hand and create a 2/2 blue
Crab creature token.)
Whenever Risen Chitin-Brute attacks, you may
put a creature card with mana value 4 or less
from your hand onto the battlefield under your control tapped and attacking. At the beginning of
your postcombat main phase, return that
creature to your hand.
