Nearheath Pilgrim
Lifelink as a shared resource rather than a printed keyword. Most lifelink commits a single body to the bargain, baking the gain into one creature's combat math. Soulbond instead lets this 2/1 hand the ability to a partner that has none, so two creatures gain life on the same swing. The pairing forms only when a creature enters: drop the pilgrim onto an existing board and you pair it then, or play your threat later and pair the two as it arrives. Once the bond locks, it holds until you stop controlling one half; it does not shuffle around the battlefield as bigger creatures show up, so the question of who gets the lifelink is settled at the moment of the trigger, not renegotiated turn to turn. That fixity is the real cost of the deal, alongside a 2/1 that trades down readily and offers nothing on defense. The pilgrim's value lives entirely in who it stands beside and whether that partnership survives, since losing either creature severs the bond and the lifelink with it. The design takes a keyword that usually rides on one body and turns it into something you assign at the point of contact, letting a fragile early drop pull its weight by lending its only trick to a partner worth keeping alive.
