Interesting. I play Mage a lot and the times when Amazons win easily is when they manage to buff creatures like using Myrto's Daughter or playing warded creatures. Also, the constant chip damage from the Bristling Pixies, Fae and the Whip is usually enough to almost kill me, and then Arkmonian Onslaught just finishes the job.

I'm kind of curious why you chose to keep Selena, though. What are you taking out to keep that card in your deck? Maybe a second copy of Nimble Pixies to combo with the Bristling Pixies or Onslaught would give you better value? Or even 2x Onslaguht for consistency?

Instead of posting all those screenshots of cards from GU Decks it would be easier and faster for you to use the direct links to the card art like "https://card.godsunchained.com/?id=2450&q=4". This way you also get images with transparent backgrounds.
