Captain America, Team Leader - Intelligence

This is Commander/deckbuilding intelligence, not confirmed market movement. Check Hero density, Avengers Assemble versions, Director Nick Fury, Animation Module combos, CardTrader supply, TCGplayer pricing, and Pricing Confidence before trusting a move.

Captain America's ability is triggered. It triggers only when another Hero its controller controls enters the battlefield.

Captain America does not trigger for himself. Casting a Hero is not enough; the Hero must enter the battlefield.

The ability does not target. The entering Hero is identified by the event that caused the trigger.

The entering Hero gains haste and vigilance until end of turn. Haste can allow attacks or tap abilities that turn; vigilance does not untap a tapped creature.

The entering Hero gets a +1/+1 counter and Captain America gets a +1/+1 counter. Those counters remain after the turn ends unless removed or the object changes zones.

Multiple Heroes entering simultaneously create separate triggers. Hero tokens can trigger the ability if they are Heroes as they enter.

Once the Hero-entry ability has triggered, removing Captain America does not remove that trigger from the stack. On resolution, the entering Hero can still gain the temporary keywords and receive its counter, while an absent Captain America cannot receive a counter.

Legendary token copies can trigger before the legend rule is applied. The legend rule is not sacrifice.

Panharmonicon and Elesh Norn can increase the enter-trigger count. Roaming Throne naming Hero can also increase the count for triggered abilities of another Hero.

Blink creates a new object and removes old counters. Phasing does not cause an entry, while reanimation does.

Effects such as Maskwood Nexus or Leyline of Transformation must make the creature a Hero at the relevant time for Captain America to trigger.

Animation Module can trigger from the +1/+1 counter placed on the entering Hero and from the +1/+1 counter placed on Captain America.

Nonlegendary Captain America copies trigger separately. A second legendary Captain America can trigger the first before the legend rule applies.

Curve Captain America into cheap and midrange Heroes, then attack immediately with new entries.

Use the counters from Hero entries to turn on modified payoffs, proliferate, and counter movement.

Use resilient Heroes, value engines, protection, and selective entry reuse to keep Captain America functioning through interaction.

Blink or recast another Hero to trigger Captain America again and reuse entry effects.

Use Animation Module token creation with type-changing effects and sacrifice altars to loop Hero entries.
