Thank you for the feedback.

significant upfront cost for these wagons, especially for those who use regular foil and/or lower level cards

This is very true. The silver lining is that players are encouraged to Level Up their Cards. The Wagon Kits are little too expensive for my taste. There are other ways small players can try out their luck. That is why I said the current Conflicts system is good enough to be continued indefinitely. Exclusive Cards, Loot Chests and Weekly Fortune Draws balance things out when looked at holistically. We do have to cater to Whales to some extent as they are the biggest investors that have the highest skin in the game.
