It was planned as a small subset of cards similar to Aftermath , but that set flopped so hard they repurposed these as an add-on to Outlaws of Thunder Junction
If youre not going to go straight for the jugular like that, then which cards you choose to give to opponents depends on what your commander incentivizes (and how mean you feel like being)
Invasion of Segovia is a perfect example: It creates Kraken tokens, so its already synergistic, and it makes fodder for Jalira, but its not a creature card, so this otherwise subpar hit wont ever be the card you find with Jaliras polymorph ability
ASHNODS INTERVENTION The first entry on the list is pretty new, and you may have missed it: Ashnods Intervention
Each turn, youll get a new 3/3 wraith token, giving you a lot of resources, and it feels like youre really summoning the Nazgl to your side
