Evelynn, Agony's Embrace

Whenever an opponent gains life, they discard
that many cards.
Ultimate — {b}{b}{b}, {t}: Target opponent gains
2 life. Then, if they have at least 1 more life than
their starting life total and their hand is empty,
they get an emblem with "Whenever you gain
life, this emblem deals that much damage to you.
Whenever any source would deal damage to you,
it deals double that damage instead."
