The card costs 1, so 2 "equivalent cards" as some like to count for 3 cards AND you need to fill the Team-up condition while neither the Gamora ally nor the Nebula ally gives you a good reason to keep them alive (contrary to the Rocket Raccoon and Groot allies).
Team-Up (Gamora e Nebula). Massimo 1 per mazzo.
Azione Eroe: Pesca 3 carte.
"Da piccole, Thanos ci aizzò una contro l'altra, ma ora siamo sorelle. Finalmente siamo unite." -- Gamora
In addition to being sort of a dead card, it doesn't even have Nebula in the artwork! Unless she's being so sneaky that we just can't see her. — Tzeentch144 · 3
