Oof, ok I love mobile games, and especially ones with build and battle types. Or match 3 puzzle ones. I am currently on Myths of Moonrise at the moment heavily invested in it. The downside to build and battle games is the people who pay to win, paying 100's a month to be the strongest. However, you can still manage it on free to play scenario might take a bit but it's worth it if the storyline and characters of the game are interesting and intriguing enough.
I was searching more to play as of recent but lately android games in google play have been hit and miss.
