Dueling nexus or dueling book for testing?

Plus it doesn't even lags which makes this way better than Book, too.

book is good if your not testing the deck and practicing the deck, nexus I would say would be used for fun or to learn a deck

Book, you can use customs are proxies for new cards if they aren't released, and you can edit specific ways to open cards, and there's a proper testing hand mode. Nexus has been shit for years, don't use it

Nexus is so much nicer. And u don’t have to worry about your opponent trying to cheat or arguing over misplays, that being said nexus doesn’t always have the newest cards
