Features request oriented play

Hi,

First happy new year and thank you very much for this wonderful tool. I love the GUI which is modern, and every work well !

I have few ideas of new features:

- Export a deck in a cockatrice format (cockatrice is a tool to play online : https://github.com/Cockatrice/Cockatrice). It's just a .cod file write as XML.

- It would be great to have a new functionality to manage combination of cards. Probably require a new screen to manage selection of cards, cost, notation, comment and explanation of the synergy etc... It would be great to have the ability to attach combinations to the decks. I understand that the List functionality can help, but a new functionality would permit more than just the card gathering.

- There is the legality for Commander, but not for Commander Duel. Both list are pretty closed, but the Duel one has more restrictions. Reference can be found here https://www.duelcommander.com/fr/banlist/ or on Mtgjson https://mtgjson.com/ (a good example is the "Sol Ring" card : legal in Commander but not in Duel)

- For collection and search, would it be possible to add the icon extension in a new column (if possible near the card name)

Thank you again,

Laurent
