Commissar Severina Raine has the same effect, but is objectively better, as it triggers for each opponent, not just the ones the creature is attacking
Theres also a Mystical Archive card in every pack, giving you one instant or sorcery spell with special art and a showcase frame
This creature can sacrifice another to put a -1/-1 counter on something and draw you a card
For this deck, I'm naturally thinking some kind of burn route with cards like Underworld Dreams and Sulfuric Vortex to consistently trigger Valgavoth's effect on every opponent's turn
This matters most to decks trying to use things like Recurring Nightmare or Genesis which can be ruined with a mass exile but will be good in almost every matchup
