Decks are custom groups of Cards. Before The New Dawn, one could put in 1-40 Cards in 1 Deck (0 was not usable due to a required Prime Card.) Since The New Dawn, 1 Deck required 3-12 Cards. Here is a list of Deck features removed/changed/added:
- Card Packs removed
- Card Limit changed
- Decks are now usable with ALL Heroes
- Universal "Attribute" removed
- Choice of Attributes added
- Gems added
- Maximum # of Cards usable halved
- Card Points replaced with Gold and Attribute Points
