As an * to the 3rd idea, they could make it so all existing excess coins get converted into universal coins automatically after the patch goes live.
You'd get universal coins depending on the rarity of the merc that had extra coins, to a 2:1 ratio; for example, 10 coins from a rare merc would become 10 universal coins, that you could trade in for 5 coins for another rare merc. Rarity scaling could use the same logic as what we currently have for merc crafting, or somewhere along those lines. For example, right now you need 500 of a given merc legendary coins to craft that merc; with the system I've outlined above you'd need 1000 extra coins from a random legendary merc in order to be able to craft your chosen legendary merc.
A solution for the coins problem would be to simply make it so you can't get any more coins for a certain merc after you've accumulated enough of them to fully upgrade everything; considering the fact that new mercs get added quite frequently, and that the popularity of the mode isn't through the roof, I believe it could be a decent solution.
That, or at least make the unowned portraits craftable/purchaseable with your excess coins.
Or, and hear me out here, they can make a universal coin, that could be traded for coins from other mercs as needed, whenever you'd end up getting coins for a merc that doesn't need them anymore.
IMHO any one of these ideas is fairly easy to implement, and would go a long way towards impimproving the experience/enjoyment of the mode.

a very fun one, bring back the nostalgia of playing the cards when they were still fresh :D
very well put together, nice little brain exercise :D
Looks good. to bad it doesn't have a spell school.
Great concept, curious to see what synergies will come along in the next year.
Borderline acceptable fluff level in the neutral package, otherwise most classes got a decent boost to their deck diversities. But that's just me.
