°•Your Inescapable Doom•°

At the beginning of your end step, put a doom
counter on this scheme, then this scheme deals
damage equal to the number of doom counters
on it to the opponent with the highest life total
among your opponents. If they are tied, you
may choose between both opponents.
If Hylia, Whole Once More is on the battlefield,
you may choose to gain that much life rather
than dealing the damage to an opponent.
