Not easily. I can get to gold 3 easily maybe gold 2 now but the competition is fierce like Sasha. I can rent though somewhat minimally and get to diamond 1 and close to top 100 in gold 1. But I have a ways to go and might be ready to compete better without renting in gold 1.
Diamond league my summoners would need to be leveled up big time or I would have to get a level 4 legendary summoner for each splinter and level all my cards up. Currently not a reality as that money(like 20g) would def go towards BTC lol
My collection can't compete in Diamond III. I make sure to finish the season in Diamond III for more rewards loot chests. I wish the Splinterlands team think about an intermediary league between Gold and Diamond, perhaps Sapphire league.
I half expect them to move up the requirements lol like 50-100k collection 😅
