Cost: 1.

Team-Up (Gamora and Nebula). Max 1 per deck.

Hero Action: Draw 3 cards.

"Thanos pitted us against each other as children, but now we are sisters. United at last." — Gamora
Nebula #22.
Daughters of Thanos

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).

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 · 11
