It's a collection of paste up with changes aimed at improving weaker factions. (although there are a few tweaks to stronger ones)
I still have the two last sets pending. (soon to be three with the upcoming one)
For instance spies took only a few changes to make it feel much better.
3x Operative - power 3 - Reveal the top two cards of each other player's deck. Place any of those cards on the bottom of their owner's deck. Return the other cards to the top of their decks.
2x For My Eyes Only - Look at the top 5 cards of your deck. Place one of them in your hand. Return the rest to the top of your deck in any order.
1x Discards Are Forever - All other players reveal cards from their decks until they reveal a minion. Discard all revealed cards.
For instance this allows spies to manipulate decks with more efficiency. In special For My Eyes Only is really good to grab (rush) specials or whatever you you might need and plan accordingly.
