Thanks for the link.
Useful for opening up new deck possibilities as it is a K value horse with "Sidekick" - the first for both keywords on this value I think. In decks where I'm playing K but not playing skilled dudes this will offer an interesting choice compared to Fancy New Hat - this is a little more expensive but provides janky movement, sidekick protection and a horse while Fancy New Hat is good for keeping you in the game.
In some matches it can even be handy to bring a booted dude in to a shootout at a deed so he can control it while your unbooted dude moves to cover other control points/income sources.
I think you can move in with this even if you've suffered zero casualties, increasing the scenarios it can be used in.
Or some weird jank involving Diable en Boite.
