I'd like to switch off tappedout for multiple reasons, but at least as of now there aren't any alternatives out there that do what I need. Some features there are nice (playtesting, the ability to log changes to a deck) but I can live without them. There are some I can't however:
1. Incomplete card versions: DeckStats has some versions of cards, but not all. Judge foils, FNM promos, pre-release versions, etc are all missing.
2. An inability to denote foils.
Now, do those thing prevent me from adding my decklist in a general sense? No, but they prevent me from adding an accurate decklist, and that's a problem because that means I need to use another piece of software to keep a accurate inventory. If that other piece of software does that then why use this one?
I'll keep an eye on deckstats because I think it has potential, but until decks here can actually show me an accurate portrayal of the cards in my deck I just can't switch.
