Based on the wording it seems like the additional cost for this card does not apply when using "put into play" effects. For Solo players you probably would only use this card via Make the Call Call for Backup etc.... to bypass the confuse status. For multiplayer games the confuse status really isn't a problem as long as you aren't the dedicated thwarter. The total stats here make Gilgamesh better than most hero cards in terms of total damage/resource and on par with Crisis Averted for thwarting. One of the more notable possibilities with Gilgamesh is Noble Sacrifice. The printed HP total is so high you could burn through several activations and then recoup 6 HP and a tough status.

Una carta genial para mazos de agresividad que juegan con eventos, solo con que juegues con x3 Vapuleo merece la pena y debería estar en el mazo decualquiera que tenga costes medios. Ideal en mazos como el de Gamora basado en eventos o el de Valkyria que necesita esos recursos extras para funcionar bien

Un Heroe barato que te salva de un ataque del villano y si te sobra una carta de agresividad puedes usarlo para matar/rematar esbirros o parar a los que hacen poco daño. Para mazos de liderazgo o de agotar un aliado para algún efecto también funciona muy bien. Su bajo coste hace que lo puedas incluir casi en cualquier mazo, parar un golpe del villano a coste 1 es siempre una buena elección.

Ultra niche card that needs to be playing a game with 3-4p, and against a villain/modular that have very nasty encounter cards that enters and stays in play (prefferably, a permanent one).

Its also a tactic, so... Cyclops (Hero)

The difficulty of this card comes in its cost. If you are able to spare 5ER on her, she alone can do 8 damage over four turns, plus 2-3 extra burst damage when she enters play.

She is also an AVENGER and an ASGARD meaning Thor (Hero) can summon her through The Bifrost; or discounted with Avengers Tower (among other avenger things)
