Common Card burn mechanism

With the amount of commons circulating do you think we need to have a mechanism to control the circulating amount of commons?

This would give more value to commons and have them be useful.

Here are some ideas commonly proposed in Discord/Telegram:

---

Combine copies to mint rare

Similar copies of the common card can be combined to mint a rare version of their card. This can be extended to higher tiers if necessary, and we can use the reference value to determine the number of copies the card need.

---

Combine/copies for exp

Commons can be used as EXP fodder for cards with bonus for similar cards, just like most many mobile/gacha games, or alternatively only allow copies of the same card to be used as EXP.

---

Recycle for XWG

This was an existing feature before, vote to bring it back. You get an equivalent XWG based on the reference price in exchange for the card.

No Change

Everything stays as is
