Playing cards based on Heroes of Might and Magic.

Hmm... What if we represent creatures with numbers and heroes from walt to king? By the way, there's an archive on one site with a very decent collection of artwork from the 5th game (including portraits of many heroes). It might be very useful for your project. Here's the link. (the archive is large, about 68 MB, I hope there won't be any problems with downloading)

In short, people are voting for the 5th game, I'm not against it, the main thing is that Nival doesn't cut my hands off.

We'll make a poker deck with 54 cards.

Next... I'm not very familiar with the 5th game, but as I understand it, there are 8 factions. Accordingly, there are three options:
1) we can make two decks with 4 factions each, with creatures and upgrades.
2) we can make one deck. With 2 factions per suit, without upgrades, with all creatures. Here, we can draw an analogy: evil faction with evil, good with good, neutral with neutral...
example >> humans + elves = diamonds.
3) we can make one deck, limiting ourselves to four factions with upgrades.
example >> humans = diamonds; Necropolis = clubs, etc.

I personally lean towards the 2nd option, so we'll put all the monsters and factions in one deck, which, in my opinion, would be more correct...

Write which option you like best, and describe which suit you think should be assigned to which faction.
