It is a good thing to get your practice in now with the Amazon decks. As more then likely they will be getting a big buff when the Core Set Refresh comes around. Then everyone will want to run Amazons. You will be sitting there with a leg up on them as you are already crafting Amazon decks and play testing them. Solid work from you.
It was my first time trying a tribe deck and it felt interesting! I would advise to try it just for the fun of it and it might be improved on as well!
Yea Amazon's are something I will be looking into for sure. I think they will be the next big meta shift
