I just got into MTG and only have about 700 cards. I have all of them typed in my inventory. One feature I think that would be really cool, is if there was a Deck Search feature that would pull decks up containing cards you have in your inventory. Sorted by most matches.   So, for instance, when filtering the Deck Search, I could select 'Standard' and 'exclusively green' and also check a box '[x] Use Inventory' and the result would come back with an extra column showing you how many you have in your inventory.

Its hard to explain what I mean, but basically as a new player, it would really be cool to be able to find decks I could possibly build using the cards in my inventory.  The only way I can do it is to copy the deck I found to my 'deck' list and then it shows me how many I have versus how many the deck has. This is ok, but would be much simpler to do it at the deck search instead of first adding the deck, checking out out, then deleting it and finding another.

My first post and my first 2 cents.  lol
