Jaces Ingenuity obviously plays amazing with counterspells, while also providing you with a good amount of raw card draw for the cost
The set has some dark overtones, so it felt like it would be a good fit for one of the uncommon black battles
That said, I personally like Nahiri, Forged in Fury for her ability to circumvent commander tax and potentially play a lot of free cards
Which makes sense when you look at its other printings: the cheapest version from Baldur's Gate is worth close to $100, for a card that is one of Magic's best dragons, an amazing treasure card, and a cEDH staple
That said, hes going to be really rough to play in the early game, and all game long there will be scenarios where playing him kills one or two of your creatures, and that will be particularly painful if your opponent can simply deal with Geth on their turn This proliferates twice which is definitely some serious upside in this set
