In the Shadows in Valhalla set in 2018, they released a number of cards related to the archetype, which of course continued the Nordic theme as much as possible
The stipulation was if Yugi lost Mokuba would cut off his pinkies, but if Yami Yugi won there would be some Shadow Game shit that was typical of the manga back then (Yami Yugi was fucking insane back then, it was pretty awesome)
If you put one of them onto the battlefield without casting it, you get the front face (the secret identity face in this set)
As MTG Arena has grown, we have accumulated extra strong sets like Wilds of Eldraine Enchanting Tales and Strixhaven Mystical Archive
You can also try to create synergies within your own deck, whether it be with Deaths Shadow as mentioned above, or my personal favourite in Legacy of casting it at your opponents end step and then cast an Uro, Titan of Natures Wrath a three-mana 6/6 creature
