A Hero tribal aggro deck that floods the board with Marvel Heroes. Captain America, Team Leader gives each new Hero vigilance and haste, plus a +1/+1 counter on both that Hero and himself, so every creature drop can swing right away and grows the team. Those counters turn on payoffs that care about "modified" creatures, which grant evasion, double strike and extra growth. Combat-damage triggers then refill the hand, make mana and pull in more Heroes, so the attacks keep feeding themselves. How it wins: Repeated alpha strikes with countered-up, hasty Heroes that are given flying, trample or double strike and boosted by damage amplifiers, overwhelming opponents through combat damage. Key roles: - Tribal cost reduction and Hero mana: Cheapening Hero spells and fixing colors with type-locked mana lets several Heroes land per turn, each one triggering Captain America, Team Leader again (Director Nick Fury, Herald's Horn, Avengers Tower). - Counter engine: Captain America, Team Leader, draw-based and ETB counter sources pile +1/+1 counters onto the team, and some cards copy or multiply that growth onto big threats (Captain Marvel, Apex Avenger, Iron Man, Armored Avenger, Metallic Mimic). - Modified-creature combat payoffs: Countered creatures get flying, double strike and trample to punch through blockers, with extra damage stacked on top (War Machine, Avenging Arsenal, She-Hulk, Wallbreaker, Thor, Asgard's Avenger). - Combat-damage value: Heroes that connect draw cards, make Treasure or mana, and cast free spells, so each successful attack refuels the next one (Professor Hulk, Ant-Man, Elusive Avenger, Scarlet Witch, Chaotic Avenger). - Hero card flow: Casting, entering or attacking with Heroes draws cards and digs for more of them, keeping the threat count high (Jarvis, Earth's Mightiest Butler, Kindred Discovery, Folk Hero). - Recursion and resilience: Fallen Heroes come back with bonus counters, and the deck keeps wraths it can rebuild from, so board wipes don't end the game (Winter Soldier, Reborn Avenger, Heroic Return, Avengers Quinjet).
