Eris, Roar of the Storm

Description

Eris, Roar of the Storm (OTC-41) is a legendary Elemental Warlock creature from the Outlaws of Thunder Junction Commander set. Its casting cost is reduced by {2} for each different mana value among instants and sorceries in your graveyard, it has flying and prowess, and it creates a 4/4 red Dragon Elemental with flying and prowess whenever you cast your second spell each turn. As a two-color (U/R) legend with a high base mana value and token-generation triggered ability, it supports spell-heavy decks and functions as a Commander or late-game finisher.
