I want to do a Jera + Blank Card break.
I've found the Blank Card in a Basement shop but I hadn't enough coins to buy it, so I had to leave it there.
Anyway I've started generating several chests with D20 + Sharp Plug and I've already exhausted the Golden Chest item pool, I'm finally getting Tresure Room items.
So I'm wondering: can I still find the Blank Card if I've already seen it (and not bought) in a shop?

Unless it was the Cursed Eye, which lets you do charged shots, I don't think it's an item at all. I just started a challenge run, and the only item I've picked up is the aforementioned Cursed Eye. But every time I take a single hit from the first boss, I'm immediately teleported out of the fight into another random room. It's making fighting the thing impossible.
So, it's either a side-effect of the Cursed Eye... Or it's a bug. My money's on the latter.
