Gryllen, Tide of Madness

When Gryllen, Tide of Madness enters the battlefield, create four 1/1 black Rat creature tokens.

Whenever a Rat you control deals combat damage
to a player, create a token that's a copy of it.


Like a seething, lumpy black carpet, the D'ivers rolled
over the cobbles. Rats, hundreds. Yet one. Hundreds?
No, thousands.
