I'm planning to get 3 copies for each card but the card trader's regular inventory makes it so hard to do so. It takes 8 hours for the shop to reset and even if it resets cards that are SR or UR are way too expensive. The standard duelist drops only a small amount of gold. Even if I can get gold through card conversion its still isnt enough. The Character level rewards focuses more on gems and character cards. The only time they get gold is when caracter reaches lvl 31, which gives out enough gold just for one SR card.
I demand a card trader event where people are allowed to buy multiple cards in regular inventory
You aren't dueling enough if your problem is 'not enough gold'. I'm trying to get 3 of each from the Card Trader too and even with how much I'm buying, I have too much gold. Keep dueling, keep trading in cards you don't need (since you only need 3 copies max of any card and cards via events are as common as ants at a picnic) and trust, you'll have more than enough gold
Well and I am playing since release, have every card 3 times and still 13.628.702 Gold left over (yes, exact). Trust me, just keep playing and u will get to that point eventually. Events always drop a 🔥 ton of Gold and I am begging konami in every survey to give me something else to do with it.
Also don't disentchant cards. I did that when I first started playing and I regret it.
