[Feature Request] Deck compare feature

[Spigushe]

It would be wonderful to have a compare feature to ... compare decks.

What it could do would be:

• Compare two or more decks
• Compare a deck against one or more TWD

The benefits from it would be:

• Have a better view of what is unique in every deck
• Have a better view of what could be called 'core'

I'd be happy to discuss it more with you if you want to
