A few moments ago I saw this post on D.Buzz by @ninjobu regarding Splinterlands:

If the new #splinterlands formats are going to exclude the cards that it sounds like they will, there are a lot of reward cards that everyone uses that won't be in the modern format. #ByeChicken #ByeSeaMonster #ByeWoodNymph #ByeOoze #ByeLordA #ByeGoblinMech

How much of an impact will this have for the players here? Worse gameplay, reduced earnings, fewer rental opportunities?
