Ivethiki, Mercurial Guide

At the beginning of your upkeep, flip a coin. If it comes up heads, until end of turn, whenever a source you control would deal damage to any target, it deals double that damage instead. If it comes up tails, until end of turn, whenever you would draw a card, scry 2, then draw a card instead.
"Be cautious around Ivethiki. He is prone to sudden violence, even if at first he seems pensive and calm."
