Bounteous Kirin

The capstone of the Spirit-Arcane lifegain payoff line, and the one that closes the loop the rarer way: not by drawing or fixing, but by banking life off the spells the deck was already built to cast. The block built a whole subtheme around the splice-onto-Arcane mechanic and a tribal density of Spirits, and this Kirin was the lifegain engine that paid you for committing to it. The design tension sits in the gain clause itself: it scales with the mana value of the spell that triggers it, so the card wants a deck full of expensive Arcane spells and big Spirit bombs, the exact cards that are slow to begin with. String together cheap Spirits and the trickle is modest; resolve a heavy top-end Arcane spell and the life total jumps in a single cast. The wrinkle worth knowing is that splice does not help here: paying the splice cost copies extra text onto a spell but never raises its mana value, so the Kirin still reads only the host spell's printed cost no matter how many splices ride along. The 4/4 flying body is honest filler for seven mana; this is a synergy magnet, not a standalone threat, and it asks you to have assembled the tribe before it earns its keep. It comes from a design tradition where top-end legendary creatures routinely carried payoffs that only materialized inside the single-minded tribal deck the block was selling.
