Jade Seedstones // Jadeheart Attendant

Craft asks you to spend a permanent to upgrade another, and most of these cards want you feeding them your worst material. This one inverts the incentive. As an artifact, it distributes three +1/+1 counters however suits the board, a flexible early investment that spreads across your creatures or piles onto one. To flip, you exile the artifact plus a creature (from the battlefield or the graveyard), and when the resulting Golem enters you gain life equal to that exiled creature's mana value. The reward scales with what you cash in, so the correct fuel is often your biggest body rather than a spare token. Note that the fuel is exiled, not sacrificed: this value engine sidesteps the death-trigger economy that most graveyard-adjacent payoffs are built around. You are not looping fodder through an aristocrat shell; you are permanently retiring a creature to buy a lifegain spike, with the graveyard serving as a second reservoir once the board thins out. Seven mana at sorcery speed keeps the flip from being a casual upgrade, which is what balances the payoff: the counters do stabilizing work early, then the lifegain arrives late, once you have something large enough that exiling it stings less than the life it returns.
