I really wanted to like this game. I love card games and the WWII genera but some bad design decisions and some truly awful l balance has created an extremely frustrating and unfun card game. I've played around 100 hours with the vast majority on mobile.

First, some positives.
The frontline mechanic is really cool and unique.
The art direction is strong, I really like the vintage style.
Generally, it is possible to build a competitive deck for free if you're willing to put the time in. Most of the in-game purchases are for cosmetics although everything in the store is absurdly overpriced making it hard to support the game even if you wanted to.

The negatives
It seems like the devs fundementally misunderstand how competitive card games work. The factions are horribly imbalanced. Usually in a card game factions will check and balance each other, with rock paper scissors counters and some factions able to do things others can't. For some reason they decided to push Japan beyond belief and give them access to everything. They have by far the best aggro, most efficient early removal, and some absurd card draw which means they never run out of steam. Why on earth does Japan get to draw 2 cards for 1 resource while the British have to pay 3?? The soviots have some really strong control tools and they're probably the 2nd strongest faction. Germany is solid but has an identity crises. Brittain has some ok defensive/heal cards but are pretty weak outside of 1 broken card that broke the meta for a solid 6 months and the devs refused to nerf until now for some reason. America has nothing going for them and you have no reason to play them outside of some mediocre ramp.

The game has a ton of RNG. You're only allowed 1 "elite card" per deck and with some of the strongest and most pushed cards being elite some games come down to who draws their elites and who doesn't. I get they were trying to make it more accessible to newer players but wining/losing off of lucky draws feels bad and that just makes the issue worse. Stack on a bunch of random effects with damage, removal, and draws, and it feels like more games come down to luck rather than skill.

The current meta is extremely unfun. I get that's subjective but basically like 2 decks that abuse broken cards have been dominating for months. Hopefully with expansions and balance changes that will change but every high tier match is pretty miserable at the moment.

This game has tons of potential, hopefully it will improve. Unfortunately right now it's a pretty miserable there's lots of other card games out there you're better off giving your time to.

You have to spend money to have a relevant deck. At least make it more accessible.

Good game. Learned easily, yet challengin.
