Summon: Esper Valigarmanda

The Saga-as-body is the design idea worth sitting with: it works in two distinct modes, first as a graveyard-hate clause that exiles an instant or sorcery from every player's yard, then as a ramp-and-recast engine that scales with the counters it accumulates. Chapters II through IV each add red mana equal to the lore counters on it, so the payoff grows exactly as the clock winds down toward the mandatory sacrifice after IV. That produces an unusual tension for a Saga: the card is most explosive on the turn it is about to die, and the mana it generates can pay for the very spells it stole. The "mana of any type" clause is the quiet enabler, letting the recast dodge color requirements entirely, so an off-color instant or sorcery lifted from an opponent becomes castable on the borrowed red. Bolting Flying and Haste onto a 3/3 turns the enchantment side into a genuine attacker the moment it lands rather than a static engine you have to protect, which is the concession that keeps the whole package from being purely value: it can end games while it churns. The structural trick is that graveyard interaction, ritual-style ramp, and spell theft usually live on three different cards; here they are stapled to one four-mana body that expires on a fixed timer.
