Dwarven Priest

The payout scales to how invested your board already is, which points squarely at the one job this was built for: shoring up a wide white creature deck against the aggro mirror. The 2/4 body makes the defensive shape explicit, a blocker that survives the early turns rather than a card that asks you to build around it, and the enters trigger sizes its life gain to your commitment. Play it onto an empty board and you net a single point; play it after a handful of small creatures have stuck and you bank a meaningful buffer at exactly the moment a racing opponent expects to close the door. That conditionality is the entire design: it offers nothing to a control shell and rewards only the strategy that needs the least help against most opponents but the most help against the fastest ones. Honest common-rarity glue, a creature whose ceiling depends on a battlefield you have to assemble first. Useful where small white bodies pile up early, inert anywhere else.
