Lunn, genesis slime

Whenever a nontoken slug or ooze you control
die, create two tokens that are copies of that creature, except it isn't legendary.
If an ability an opponent control would
cause you to discard lunn or another ooze or slug, instead put it onto the battlefield.

"Lunn has lived since the start of the multiverse,
Even though it may look weak, it's descendents exist everywhere"
