Mantis Lords

Vigilance
When Mantis Lords attacks, create two tapped
and attacking 3/3 Mantis Lord creature tokens
with "sacrifice this creature at the beginning of
the next end step."
Whenever Mantis Lords dies, you may search
your library or graveyard for a card named
Mantis Claw, reveal it, and put it into your
hand. If you search your library this way,
shuffle it. Create three Treasure tokens.
