A card with a stamping error cannot be sold as Near Mint (NM) , even if it is physically perfect
Whenever you cast an instant or sorcery spell, create a 3/3 black Wraith creature token with menace
Additionally, while this card may demand a rather steep mana cost, as Demons are rather costly, this spell can be strategically cast once you've built up your board with a few Demons, ideally catching an opponent or two who'd over-committed to the board off guard
Draw engines like Sram, Senior Edificer, Akiri, Fearless Voyager, and Puresteel Paladin keep your hand full as the game progresses
If Venser's triggered ability targets a spell cast with flashback, that spell will be exiled instead of returning to its owner's hand
