Sustenance

Trading lands for combat power was never a generous exchange rate, and this enchantment puts the arithmetic right out in the open: a mana plus a permanent for a single +1/+1 that evaporates at end of turn. The pitch is repeatability. Keep paying the and feeding it lands, and the same enchantment keeps pumping, so a deadlocked board can be cracked by spending your manabase one point of toughness at a time. The friction is deliberate and severe. Lands are the resource a green deck least wants to dismantle, and a temporary boost that costs both mana and a permanent demands you mortgage your future for one combat step. The effect is open-ended, but every activation deepens the hole, so the payoff only arrives when the game is already tight enough that one more attacker ends it. This is an older school of green combat enabling, from before pump migrated toward cheaper self-contained creatures and one-shot tricks: permanent-based effects carried a built-in tax precisely because they were unlimited. The card converts the count of lands you own into raw stats, slowly, and only when you have nothing better left to do with them.
