Ogres have just become Tier 2.5 in the 2nd season.
E.g. you are playing a standard League format = 10 participants/ 9 games.
You want to get those 12 spp, because of the Block, but you don't want to "overtop" at 18. So you try as much as you can to store those spp and keep it low on Ogres.
Next season start: You buy all of those Brogres back, each now standing + 20k top of their basic value and and all of those guys who have 12-18 spp you give them block at the start of the new season. In theory 6 Brogres with Block at the start of the 2nd season.
