Herigast, Erupting Nullkite

Description

Herigast, Erupting Nullkite is a legendary Eldrazi Dragon from Modern Horizons 3 that costs {9} and is printed as a normal mythic creature card. It has Emerge and a triggered ability that lets you exile your hand when you cast it to draw three cards, and it grants emerge to each creature spell you cast, setting those emerge costs equal to their mana costs. It also has flying and a 6/6 body, enabling a late-game evasive threat and providing synergy by enabling other creatures to be cast using emerge.
