While it isnt quite as crazy, Displacer Kitten almost gives me fixed Paradox Engine vibes
The card will have to compete with Atraxa, Grand Unifier, which frankly feels like a losing battle, but the ability to hose opposing graveyard decks and the Ward ability Valgavoth possesses could allow it to be sideboard material
Why do I like this card
To support this "discard haymakers, punch people in face" game plan, we're going to discard and buff Volrath with cards like Scavenged Brawler, recur our huge haymakers with Gix's Command, force our opponents to hand over our haymakers with Protection Racket, and oh yes maybe double kill opponents by casting Essence Harvest after pumping Volrath
Additionally, each sword has its own unique ability that is triggered upon the equipped creature dealing direct damage to an opponent, and the cost to equip the sword is always two mana of any color
Such great strategy marred by an extremely heavy buy-in and upkeep
