Drey Keeper

One card that becomes three bodies on entry, then hands you a way to make those bodies matter: the 2/2 Elf Druid is incidental, a delivery vehicle for the two Squirrel tokens that arrive with it. The token spread is the setup, and the repeatable activation is the payoff. For four mana you pump the whole Squirrel contingent and give it menace, the keyword that punishes a defender who can only chump one attacker at a time. Folding the maker and the anthem into a single card is the design choice worth noticing: a go-wide deck usually splits those roles across two slots, one card to produce the swarm and another to make it lethal, and this collapses them into one signpost. Menace is what turns the pump from incremental to game-ending, since a board of buffed tokens that each demand two blockers converts a stalled ground stall into a clock the opponent cannot profitably block through. The card sits squarely in Golgari's small-creatures-matter tradition, where individually irrelevant bodies become dangerous only in aggregate; the swarm-and-pump loop is exactly the shape that archetype wants. It is a build-around more than a standalone threat: a card that declares the Squirrels are the deck and then supplies both halves of that promise, the population engine and the finisher, without asking you to find them elsewhere.
