pile. There are 30 of them. You get one via a card saying "gain a Horse" or something. If the pile is empty you can't gain one, but let's hope that doesn't happen much. So Horse is a one-use ; it puts you up a card and then is gone. Or, you know, you don't have to play it; you can Remodel
it or something. It's there for you. Once in your deck, it's just like , from ; it turns out, they were experimenting on Horses. Eight total kingdom cards

 Secret history
The other idea was for a particular way to do "+1 Card tokens
." I considered them for , but it didn't sound great to have a pile of tokens you could constantly consider cashing in for cards. What I ended up doing for Renaissance was , which just happens at the start of a turn. But another approach was to have a pile of one-use
you could gain. It was like a +1 Card token, except different in all the ways it's different - you can only use it when drawing it, you can it, and so on. There wasn't room for a big pile of those in Renaissance, though it got . So this was another thing to try right away, and right away I liked it. Horse itself started and ended costing , but I tried having it cost , to make it weaker with trash-for-benefit

"Gain 3 Horses" is like ... but it doesn't draw dead cards, and doesn't draw at all the first time you play it, and well more differences, and stuff. It was a pretty neat variation on and still really simple. And then the variant was nothing like . It was pretty neat too. Well as you may have noticed, these cards aren't in the set. They both just produced too many Horses. Another way "Gain 3 Horses" is different from is, it takes longer to resolve - not just playing it, but playing it and playing the three Horses. So in the end there are "Gain 2 Horses" cards, but no 3, and only gets to really go nuts gaining Horses.
