Yes, I am re staking almost all my SPS back in staked so the staking APR and price appreciation over time will benefit me well, I hope at least.
For you issue, I would suggest to see what cards and lineups players using in your league, just battles of the top 20 that would help you. I also love the core game as well so focused on my SPS and card collection as always.
And about the EOS, I am seeing others to use this term as end of season so thought to use it that way 😅
