Crawling Swarmlord

Whenever you sacrifice a land or creature, create
a 1/1 green insect creature token.
Sacrifice a creature token: Draw a card, then
discard a card.
Segmented (When this creature dies, if its base toughness is 2 or greater, create a token that's a copy
of it, except it has base power and toughness X/X,
where X is half this creature's base toughness,
rounded down.)
