Japheth, Relentless Regulator

At the beginning of each combat, you may
attach up to one target equipment in play or
in a graveyard to Japheth. If you do, Japheth
untaps and gains first strike until end of turn.
{t}: Deal damage equal to Japheth's power,
divided as you choose among any number
of targets, then sacrifice all equipment
attached to Japheth.
"I hope that's registered." —Japheth
