I am 100k might and need help with fortress feud teams. I only have sk, pd, dd, ghoulem, grim, harpy, cupid, valentina, aries, , medusa, all the shard heroes and a few more like snowzilla and others. Please help.
Can send me a screenshot on line @Gamer35768.

No one can really give you a definitive answer to this.  There are just too many factors.  That being said, my Team 1 on your account would be:  SK, DD, Aries, Ghoulem, Grim, and Val.
