Overlord of the Boilerbilges

Impending 3 - {r}{r} (If you cast this spell for its impending cost, it enters with four time counters and isn't a creature until the last is removed. At the beginning of your end step, remove a time counter from it.)
Whenever Overlord of the Boilerbilges enters or attacks, create a 1/1 red horror creature token with haste and "This creature can't block".
