Moter

When Moter is sent to the graveyard, make 2 1/1
Fly tokens. If Moter was destroyed as a result of
combat damage, the created tokens come into play
attacking and are unblockable until end of turn.
"When too many flies get crammed into too small of a
space, the ways they save space are ingenious. For
example, two flies jammed together in one place
merge into a Moter."
