Ok thanks! I also find that it makes a lot of AI3.. but I'm not sure to make more than 50% success against AI4 :/
I'm thinking about cards I should upgrade at the beginning, but it's not easy, I have 2-3 decks in different elements, and I don't know which one I should focus on!
I have a pretty good one based on Adrenaline and Scorpions/Frog, but I have several possibilities with gravity! Any idea to help me to choose?
Upgrade your electrum hourglasses
first. At least 2 of em. Then make a farming FG deck and win upgraded card spins from em.
consider to upgrade the likes of elite firefly queen, elite oty, quantum pillars, SoGs, supernovas, etc.
Otherwise you might regret em later, and uh, don't upgrade nymphs.
