Anything honestly as long as it's fun.
Didn't know this was on mobile. Getting it.Gotta be Fire Emblem Heroes.
They give away a LOT of summoning Orbs, there is a huge variety of characters and events are always going on!
Doesn't seem like it's on Play Store. Shame, wanted to play that back then but couldn't find a copy.You can get Ghost Trick on Mobile.
Ghost Trick is one of the best games of all time.
Ergo, get Ghost Trick.

Yeah, this is real fun too. I like it more than vainglory.
