RE: Splinterlands: Dark Assassins Guild is Recruiting!

I received an invitation once. Our "guild has won spoils of 28 Crowns in the latest brawl." I informed them that I could not participate for now, not only because of my schedule but also because my deck is still too weak. My winning rate in Gold 3 dropped to just 50/50. I expect that the battle in the brawl is more intense and competitive. I don't want to be a burden. I will work on upgrading my cards to be strong enough even for Silver I.
