Ant Colony

At the beginning of each upkeep, choose a player
at random. The chosen player creates a 1/1
colorless ant arifact creature token with haste,
skulk and "This creature attacks each combat if
able." for each chaos counter on ant colony.
Chaos 10 — At the beginning of your end step,
put a chaos counter on this permanent, then, if it
has 10 or more chaos couters on it, sacifice it.
