언매치드: 로빈 후드 vs. 빅풋

You get exactly two actions each turn (each action can be a Maneuver, Scheme, or Attack) and you cannot take more than two unless a card effect specifically changes that. (Rulebook p.5)

Yes; the Maneuver action instructs you to draw a card and then move your figure. (Rulebook p.5)

You may discard cards for Boost as described on the Boost rule—discarding cards adds Boost for movement (and other Boost-eligible effects listed on cards) according to the card text. (Rulebook p.6)

Follow the timing words exactly: resolve effects at the labeled timing in the attack resolution sequence and apply damage and other effects in the order specified; see the attack resolution timing and order rules. (Rulebook p.7)

When a sidekick is defeated it is removed from the game (it does not return); if a hero is reduced to 0 health their player/team loses. (Rulebook p.8)

You must follow the game's targeting rules and the card's range: adjacency and multi-zone layout determine what you can target, and ranged vs melee icons affect valid targets—see the Spaces/Zones rules and the attack targeting rules. (Rulebook pp.4, 6)
