Good functionality, but some annoying issues
Pros Can easily scan 90 percent of your cards. Uses scryfall database. Can export cards to csv and then import card list to other systems (e.g. deckstats). Shows cards prices. Set database with set filtering by name. Good card filter Deck Builder Cons Does not recognize foreign letters, thus have to use search function or set database to add these cards. Search filter only shows all versions of a card, if the name is exact, but not if this exact name is part of a name of other cards (e.g. will show all versions of arrest, but only one version of tremor because of cards like impact tremors, making it hard to add the card erdstoß) Can only add special cards like tokens, emblems in set lists. Can only efficiently add basic lands in set lists. Non registered cards from card database are greyed out, making them hard to see. No search function in set lists. Some language versions of cards doesn't exist. Blame gets shoved on scryfall, but not true every time. Import into deckstats had to be conducted there, because app creator wouldn't add needed export variant (still problems with some cards). Even though most cards have prices in detail view, the overview only shows prices of english and some special cards, e.g phyrexian language. Overview always has filtering enabled, but some cards (e.g. emblems, dungeons) cannot be filtered. Therefore some cards can be added, but won't be visible outside of set lists. Cannot add double faced tokens (e.g., from collectors booster or commander decks) unless some minor exceptions. Need to add each side as separate card. Deck Builder won't accept cards upon scanning. Need to scan first and then add the card. Deck overview lacking. Can only add cards up to 4 times. Creator won't respond to tickets or even give negative response. Will point all card related issues to scryfalls database, but wouldn't respond, even if the fault lies with cardbinder.
