Adding a bonus curio/rare card after replaying the game to improve novelty

[SkylarkHYP]

What about an option that lets you start with a random bonus curio/card to improve replayability .
I kinda got the idea from "peglin"'s (A blessed run), "Just King"'s (Bonus item), and "Backpack hero"'s (Mathew's blessing)

The main premise is that after playing 1 run, an option would be unlocked to give a random change from the game, giving the player an alteration of gameplay from a mechanic that already exists in the game.

I'd also suggest adding a special hotkey to activate this, as players who've already played the game would get annoyed by not having this feature for things like public computers or etc. (ex. Pressing the M key in Backpack hero sends the player directly to Mathew's blessing)
