There are no mobages/mobile games like Aigis in english. The only games like Aigis for phone are in japanese, so I can only say good english mobages. You can play Kingdom Hearts Union Cross, Digimon Linkz, Dragon Ball Z Dokkan Battle (is very generous with gacha!), Sword Art Online Memory Defrag (good game, but only play if you can with almost shitty rate gacha), Phantom of the Kill or Fire Emblem Heroes if you like tactics games, Yu-Gi-Oh Duel Links, Tales of the Rays (very good mobage, almost has the same feeling like playing a real Tales of) and finally Crash Fever which has a really good OST and good designs (also played by a lot of F/GO players).
