Fendeep Summoner

Animating lands as creatures is one of the oldest manabase tricks in the game, and most cards in the lineage point it at the opponent: turn their lands into bodies so a Wrath of God or an Earthquake catches them. This Treefolk Shaman repurposes the idea as offense. The tap ability turns up to two target Swamps into 3/5 Treefolk Warriors, and because the activation taps the Summoner rather than the lands, the freshly animated Swamps can swing the turn they transform. The catch is the same one that governs any attacking creature: those Swamps tap when they attack and stay tapped until your next untap step, so the alpha strike costs you two lands' worth of mana through the opponent's turn. That window is the price of the offense, and it makes the timing of the activation a real decision rather than a free clock. The 3/5 frame is sturdier than most land-animation payoffs, but it is a payoff with teeth showing: an animated Swamp is a creature in full, and a removal spell aimed at it sends the land to the graveyard rather than reverting it, costing you both an attacker and a piece of your mana base. It sits in a small Treefolk-tribal current built on the idea that flooding the board with forest-folk should let the ground itself stand up as more of them.
