LOL, you got owned by a proper meme deck :)

People were trying this early on when the DA set came out, but they quickly realized the deck was too slow and would lose a lot to aggro...

Your opponent made some questionable choices like adding Narcilla to the deck. In this case you really want Scythia to be the only Amazon in the deck so it always gets picked up by United Reinforcements. Playing Scythia as early as possible is key to winning games.

Your own deck has some questionable choices, like Giramonte or just a few Atlanteans. By trying to do a lot of things in the same deck, you will never do any of them well and the result is a weaker deck.

I'm not even sure what is your win condition because I don't have your decklist. It would be great if you could add a screenshot of the decklist to your posts, along with the deck code.
