Blue Stake’s gimmick would now be to change all big blinds into being mini boss blinds. They’re still skippable but have minor effects tacked onto them. The same one can spawn multiple times a run.
Here’s a few I thought of (unless otherwise specified, they have 1.5x base blind size)
Indigo Blind: -1 hand
Crimson Blind: -1 discard
Marigold Blind: 1.75x base blind size
Jade Blind: -$1 per hand/discard used
Charcoal Blind: Leftmost and rightmost cards in hand are debuffed
Pale Blind: 0.5x money earned during this blind (rounded down)
Lavender Blind: Applies perishable to your leftmost joker
These aren’t supposed to really be run enders but more so just nuisances
