I really like conflicts, but I think they are far from "as perfect as can be."

One of the biggest flaws IMO is the significant upfront cost for these wagons, especially for those who use regular foil and/or lower level cards. The number of wagons needed to generate a single card can be extremely high.

The entire setup is designed around whales and land holders. The low to mid level spender is more likely to lose money on these, even though they see them essentially promoted as extra value for their cards.

For example, imagine if you need to setup 20 wagons to get a single airdropped card. At current prices that is about $130. After you repair each time, you might be looking at $5-$10 in net profit for each airdrop. And that's assuming you make a profit, because multiple airdropped cards have been worth less than the current wagon cost. This means it would take multiple sets to even get to a break even point for using wagons. Most players would end up leaving the game before actually getting there.

If wagon costs are going to be paid up front instead of after generating a card successfully then we really need the ability to resell these wagons when we are done with them. Otherwise players will almost always end up with wasted costs in the end.
