You could even run them alongside Basic and Stage 1 Pokemon for a more free-to-play friendly deck, as we have suggested below
Kashtira Kashtira is definitely the deck to beat in this format
2 mana to cast and equip this Legendary card is already a good rate, and the fact that it generates 2 counters, which you can use even while it is unattached , anytime its equipped creature deals combat damage (thats attacking OR blocking) is insane
The actual battlefield has helpless refugees being hunted down and infants being carded

It definitely is quite flavourful, and the effect has the Dark Maze attack exactly once (Walls can't attack, remember) before being exiled from the game entirely, representing the shadows fading away
