Rating: unplayable, not even on Gloria.

Encounter card reordering is only useful in low player-counts. This is because in low player counts:

• controlling the variance of the encounter deck is more important (when you don't have other players to bail you out),
• looking cards means knowing 2 turns ahead in 2p and 5 turns ahead in solo, but only slightly more than a turn in 3p/4p
• moving a card to the bottom of the deck can mean it never shows up, while in 3p/4p you'd usually draw through the encounter deck

However, at low player counts actions are also much more precious. You cannot afford to spend 2 actions 2 resources and a card to trade an encounter card for a weaker one. Most encounter cards don't even cost you 2 actions 2 resources and 1 card.

This is one of those cards that makes you wonder if the designers playtested it before release.
