I have 2 suggestions:
1) All players that love to blow money ie. myself, DrRick, Proton, Bakiz, Harcourt etc... everyone join one guild and then BAM no competition.
2) Before Guild wars start, quit your guild, start a 2 person guild, contribute over 50k and both you and a friend guarantee yourself a 7 star card.
I'm at a total loss for the broken guild war mechanics. I'm better off competing on my own, guaranteeing myself a 7 star card, and using in game messaging and this board for social aspects. I don't really NEED any other cards, including what's available in shop so I might as well pursue this for future wars.
This is garbage.
