Hello, and I am happy to be back, though I didn't play all that long when I was here. I use to play years ago till my tablet ran out of room, now I have one that allows me to play again. So a question is there an event pull that makes it easier to get Shiva, or should I pull on the rare egg one cause it's the best shot I have? Also, is there a list of just the 7x6 leaders? And is there a reason to keep duplicates of good units? Like do they power each other up if I fuse them together?
