My options:
Heroes V WGE (Online)
Goal: obvious
+Well, it's still Heroes. And many people played this particular installment.
+The game has been significantly changed; the gameplay has been improved for online play.
+The mod focuses on short games (up to 1 in-game month).
+And yes, simultaneous turns work.
+Relatively low skill level of potential participants, which will avoid long, tedious turns.
-For many, Heroes is really a thing of the past.
-Even these short games in Heroes are clearly longer than card game matches.
-Problems during connection? You'll need to set up a local network using Hamachi or something similar. I also recently learned that some pirated versions of the fifth game behave strangely online. So you'll have to keep track of what's installed.
-The mod is in beta. Although the balance should be better than the original anyway.

Goal: defeat everyone
I tried this game for a bit (Medj told me it was released), and here’s what I want to say.
+A card game similar to Shadowverse, but with slightly different rules.
+Short, interesting, interactive matches.
+Many people know this universe, these characters, all these Ecaflips, Iops, etc.
+Cool visuals (in my opinion)
-The game is still under development.
-No other drawbacks yet.
Clash of Heroes (online)
I read that you can play it online via LAN. So, it's quite an option.

+Simple but interesting tactical gameplay.
+Short games
+Again, I like the look
-You have to buy the game or download it from torrents.
