Gold

Gold is a resource used extensively in Marvel: Contest of Champions. Gold is used to do things like Level Up and Rank Up Champions, is awarded in Arenas if you have won at least two battles, and from the Golden Crystal, Greater Golden Crystal, and Uncollected Gold Crystal (more notoriously from the Arena Crystal, Uncollected Arena Crystal, and Thronebreaker Arena Crystal).
