Its a nice game, love the art and animations, story is quite good but a bit plain as well. It quickly turns into a grindfest, only way to build your deck is to run through Chaos mode which can take an hour of dedicated play, theres no auto mode, so it gets quite boring quickly if you ever want to change your deck, they have improved this but not too much. The real pain point is the monetization, its expensive, roughly £25 for 10 pulls, so you can't chase every new character like other gachas.

Drop rates are terrible, the shared pool between Partners and Combatants make pulling the real Nightmare of this game. Not even pity rate guarantees a 5 star banner item. The progression continues to be slow, with no combat speed increase nor automatic play in some modes. You may find fun in combining, refining decks, but it seems the effort to do so is immense.

A good game in need of serious work. So to start off, I enjoyed the gameplay loop a lot, however, I've hit a brick wall with progression. Once you get to around level 40 with your agents the cost to level them up ramps up significantly. As a result I can't continue with the story because it takes so much effort to get the resources to level and a lot of the content is level gated. Really disappointing.
