Descendants' Fury

The elegant part here is that combat damage becomes a tutor and the sacrifice is what pays for it. Most reanimation and cheat-into-play effects ask you to fill a graveyard or discard something first; this instead consumes an attacker you already committed to the board, then digs for a creature sharing any of its types. Reliability tracks tribal density: a creature with a single niche subtype whiffs deep into your library, while a card packing overlapping types (Human Warrior, Elf Druid, Goblin Rogue) turns nearly the whole creature base into a live hit, dropping whatever you find straight onto the battlefield instead of into hand. The economics reward attacking wide with cheap, disposable bodies and trading them up into your top end: connect, sacrifice a one-drop, land whatever expensive creature happens to sit near the top. Because it fires every combat (once per triggering swing) a board of tokens sharing a type grinds through your library as a repeatable engine rather than paying off once. The random-bottoming of the revealed cards costs you a little knowledge of your deck's order, but the trigger only cares that a shared type exists somewhere in what you reveal. This is built for a tribal-aggressive shell that wants its attackers to matter twice: once in the red zone, once as fuel for the next threat.
