Dregliege

Rats you control have Skulk.
Whenever a Rat you control dies, Dregliege gets +0/+1 until end of turn.
Whenever Dregliege is dealt damage, create that many 1/1 black Rat creature tokens.
"A rat of white, a rat of black, a rat of brown or gray - A million million starving rats have
gnawed my names away."
