Chainer, Nightmare Adept

Most graveyard-recursion designs ask you to protect your best threats and dig them back with a spell. This one inverts the pressure: the discard is not a downside to be minimized but the fuel the whole engine runs on. Pitching a card grants permission to cast a creature from your graveyard, and you still pay its full mana cost, so the ability is not a discount but a re-access point: the yard becomes a second hand you can draw a threat from once per turn. The haste rider is what makes the loop worth running. Because anything you recur was cast from the graveyard rather than the hand, it arrives with a pulse and can attack the same turn instead of idling through a sorcery-speed lull, and the two abilities feed each other: the discard that fuels the graveyard is the same action that stocks it for next turn. The once-per-turn clamp on the recursion is the restraint that keeps the queue from spiraling; you get one re-cast per turn, so the deckbuilding tension lands on which creature is worth discarding and re-buying rather than on how many times you can chain. The 3/2 body is beside the point: the reason to run the card is the rotation of hasty reinforcements it turns a graveyard into, not the beatdown it offers on its own.
