## Deck Builder for Union Arena Reviews in United States

### *---- "What are others getting that I’m not?"
I don’t know how all the reviews for this are so good??? I have not been able to get this app to work properly yet!

To add cards to my collection, it shows the camera, but doesn’t let me take any pictures! 
Somehow the single deck I tried to add copied itself hundreds of times and now the deck list is completely filled with an invalid deck that I can’t even delete. I’m unable to delete the deck, so I tried to just delete the account and restart. Won’t even let me do that! Whenever I try to search something it just spins but nothing ever comes up!

I love the idea of this, but so far it’s been completely WORTHLESS. Glad I didn’t put the money into removing ads or adding subscription or I’d be seriously ticked off
-- Colejamum, 2026-07-16

### *---- "usless"
it didn't even load any cards! and i could not see any posts (most likly cus u can't even create a deck!) plus i could not sing in! really
 bad
-- derpyslime0, 2026-07-13

### ****- "???"
The app is nice but I don’t know if I can trust it to buy the decks or cards, idk if I’ll get scammed
-- $$$moneyhungery, 2026-06-30

### ***** "My Favorite Union Deck Builder"
Fantastic app. Makes it super easy to filter through different series and look up alt arts. I like the ease and simplicity of using this for deck building especially since another big website overcomplicated and ruined their own user interface a few months ago.

The one thing missing is that the TCG prices are not regularly updated. Currently, most card prices on the app are nearly 4 months old. Newer series don’t show a price at all. The app does provide a direct TCG Player link on each card, but I like having the price shown for each card in the app for ease of use. If the app continues to show a price though, I would like to see it updated more regularly, even something like once a week. If the prices stay 4 months old I would rather they got rid of them and just kept the bare link.

If they update that one feature and I didn’t have to switch back and forth between multiple apps, this would definitely be 5 stars.

Regardless, I tell my friends to use this app and I recommend you get the ad free version



Update: Thank you for the developer response, price issue has been fixed and working well lately! Great app!
-- InboundsFuture1, 2026-02-25

### *---- "Maybe incompatible, maybe bad?"
Every time I try to make a deck, the app won’t let me add any cards to it. It keeps saying I have no compatible decks to put them in even after I make multiple decks with the required series as the selection. Maybe it’s just incompatible with iPhones, but a deck builder that you can’t use to build a deck kinda defeats the purpose in my opinion.
-- Momofze, 2026-02-18

### ***** "Amazing"
It’s been amazing. I make my decks then I buy them. Simple as 1,2,3. There was a bug and the developer fixed it. Thank you much love and plus ultra
-- MatthiasRoyalty, 2025-03-23

### *---- "Crashing issue"
Every time I tap in a deck to view. The app just crashes.
-- FranklinJM, 2025-03-05

### *---- "Don’t bother"
I understand it’s fan made but it uses A.I
. 90% of my scans were incorrect. Only can scan ten cars free 5$ for only 250 cards a month. That isn’t a lot at all for a collector.
So I don’t see the point of it .
-- jason*82simmon, 2025-02-19

### *---- "Terrible deck building"
The app doesn’t allow for a seamless experience of inputting cards in their amount or exporting the deck list as well. The navigation is terrible for adding cards as well as you can’t separate by sets either
-- Anon tom, 2025-01-05

### ***** "Awesome"
The Deck Builder app is a fantastic tool for trading card game enthusiasts, offering an intuitive interface and a comprehensive, up-to-date card database. The drag-and-drop feature makes deck building effortless, while the robust search and filter options allow users to quickly find the perfect cards. It’s an invaluable resource for refining strategies. Overall, this app enhances the deck-building experience, making it a must-have for both casual players and serious competitors.
