Oyobi, Who Split the Heavens
The payoff every Spirit-Arcane deck was building toward. The block's tribal engine handled chaining cheap effects together with splice; this is what made the chain produce a board. Each time you cast something with the right typeline, a 3/3 flier joins you, so the cantrips that lubricated those decks and the cheap spells that fed the engine each leave a body behind. Note the boundary: splicing a card onto a spell does not count as casting it, so a single Arcane spell carrying three splice attachments triggers Oyobi exactly once. The token output tracks how many spells hit the stack, not how much value you stacked onto one of them. The 3/6 frame is doing quiet work: at seven mana it sits above most of the burn it would otherwise dodge poorly, and the toughness lets it block while the tokens it spawns do the attacking. The real design tension is sequencing. Oyobi rewards landing first and casting after, which inverts the usual instinct to deploy threats and protect them; the engine wants the legend down and a fistful of spells still in hand. Where the tribe's other lords pumped or recurred, this one converts spell velocity directly into permanents, the durable answer to how a spell-heavy deck closes a game without running out of bodies.
