Strange Augmentation
Delirium payoffs come in two shapes: cards that gate a whole spell behind the threshold, and cards that stay castable but reward you for hitting it. This one is the second kind, sharpened almost to a knife-edge. For a single black mana you get a flat +1/+1, a buff so slim you would rarely spend a card on it, but the moment four card types sit in your graveyard the enchanted creature swells by an additional +2/+2, turning a marginal Aura into a burst of stats wildly out of line with its cost. That conditional is the entire bet, and it is a threshold you cross once and hold: milling, cracking fetchable lands, and casting spells all feed the bin, so the count climbs toward four and, absent graveyard hate, stays there. As a sorcery-speed Aura it commits ahead of the fight rather than answering it, and it carries the usual cheap-aura liability: an opponent can kill the creature in response and eat two of your cards for one. The payoff math changes character depending on which side of the threshold you sit. Below it, this is close to unplayable. Above it, it is one of the most aggressive black clock-accelerators a graveyard-diverse shell can field. That makes it a builder's card rather than a filler's: it earns a slot only in a deck already engineered to stock the bin with variety, where it reads less as a standalone spell and more as a dividend paid on work the engine was doing anyway.
