I'm trying to understand where people are coming from with their "no", but I can't.
Let's take a simple example.
I have an upgraded Miracle that I don't need and want to get rid of. Instead of selling it in the bazaar, I can sell it for more electrum to a user who needs it. I still had to roll the miracle to begin with and the user still had to farm his gold.
Cards won't be "less" rare. The roll frequency doesn't change, you still have to roll the cards. But it lets someone spend electrum to avoid having to roll when he needs the card immediately.
Also it's not like it would be hard to fix any abuse such as making multiple accounts to get quick quest reward electrum. Simply make quest electrum unusable in trades/transfers.
I'm not for card auctions. That's easily abusable. But card TRADING however should be welcomed. If I have 4 firefly queens that someone needs and he has an SoG that I need, why can't we just trade? Hell, why can't I just give him 1500+ electrum for it?
1) Quest money cannot be tagged. If it could then it can be laundered easily in the bazaar.
2) Rare weapons would be cheap and common through the Rare Weapon quest.
3) All other Rare cards would be cheap and common through the oracle.
4) The bazaar would be useless because this "trading" is strictly cheaper.
So under your specific example the bazaar is the useless system and the trading is broken
This does not even mention the burden caused by the thousands or more dummy accounts made to break the system.
5) It looks like an infinite money scheme can be created by trading All of a starting deck for a Pillar.
Ah those are pretty good examples.
Tho, I don't see how most of them can't be fixed. Tagging quest gold no matter what you do with it along with your starting cards is codable.
Also bazaar still has its use to buy existing cards or selling low cards that nobody wants or for which you'd not want to engage in a trade.
I'm not trying to backtrack everything you're saying. I get where you're all coming from, but you can't deny that by fixing the issues, having a trade system would be amazing.
