User Reviews

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!

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.
