Deeproot Wayfinder

The two-drop that turns a fetchland click or a sacrificed manland into a recurring resource, but only if it connects. The surveil-then-reanimate-a-land trigger fires on combat damage to a player or battle, and that connection requirement is what balances the effect: this is a body that has to attack and land its hits to earn value, not a passive engine that grinds from the safety of the backline. A 2/3 is built precisely for that job, big enough to trade up or survive a swing back, small enough that nobody feels obligated to answer it before it has done its work. The surveil sets up the graveyard the same beat it feeds from it, so a fetchland you cracked early becomes a land drop a few turns later, replayed tapped. Merfolk who care about lands is a narrow enough space that the effect reads modest, but the loop it enables (attack, dig, rebuild your mana) favors decks running lands with enter-the-battlefield or self-sacrifice value over raw ramp. The tapped clause keeps the recursion from ever being free tempo: you get the land back, just never on the turn you would most want to spend it.
