Dreadhorde Invasion

A recurring token generator that pays for itself in life, one point per turn, and grows a single body rather than a swarm. That last detail separates it from every wide Zombie-maker that came before: Amass funnels every upkeep trigger into the same Army, so what starts as a 0/0 becomes a genuine threat by the third or fourth turn instead of a pile of chump blockers. The second ability is the payoff clock and the safety valve at once: once that Army crosses power six, attacking with it starts refunding the life you have been bleeding, turning a slow drain into a self-sustaining engine. The tension is entirely internal. Left alone, the enchantment keeps taxing your life total whether or not the board state wants another counter, and closing the game before the arithmetic turns hostile is the whole game plan. It pulls hard toward attrition builds that treat life as a resource to spend rather than a total to protect, and it rewards decks that can guard a single scaling creature over decks that flood the board. Removal aimed at the Army resets the growth but never the enchantment, which keeps rebuilding from zero. That resilience reads modest on a two-mana permanent and plays out far more grinding across a long game.
