Show me your best cards!

What is your favourite card to play?
What is your most value-able?
What is your rarest?

For me its all the same. The queen goes into all of my earth battles and adds some shield stability.

I haven't played for long and haven't bought a lot of decks yet so still building decent cards, but below is top 12 sorted by Rarity.

So me what you've got and tell me your favourites!
