This is the deck I've been using for AI3's and I've found that I usually win every 8 out of 10 matches against AI3's. The downside is that it can't get Elemental Mastery's very often, if at all, but it's an easy to use deck to beat AI3's repeatedly, while being non-upgraded. If anyone knows a AI3 farmer that most often gets Elemental Mastery's or one for AI5 that gets EM's a lot it would be appreciated if someone would message me and point me in that direction, I've been checking out some of the AI3 decks and AI5's and I'm not sure which one's actually work, now, because a few that I've tried haven't worked at all.
