Banish and rerolls for perks

Most roguelikes have a reroll and banish system. Banish you either use a currency or use money to banish a single perk from the pool from the run. While reroll you can have a new set of available perks. My idea would be.

• You have at most 3 banish rolls per run when used on a perk it burns it making it unavailable for the rest of the run but leaving the others to choose from

  You can have it where every 2 complete runs you do unlocks you a banish roll max upgrade up to 3. These rolls would reset to your available max at the start if each run. Gives more reason to complete runs.

• Rerolls can be done up to 2 times a run using 1000$ X the number of times rerolled but when you reroll it is a new set of perks.
