Played some Legendary (not pictured) mixing everything (including Villains) up through Secret Wars. Was a really disconnected deck, but SHIELD managed to stop Dr Strange from crushing Hydra (why they would do that is unexplained).
Then some 3-player Roll for the Galaxy (also not pictured). I managed a win getting a bunch of planets that provided red dice and then the development that gave me 2 VP for every 3 red dice I had.
Then 3-player Valley of the Kings. I love this little deckbuilder. Won that against two newbies.
Finally, some 3-player Machi Koro, with both expansions. I had an early lead but that Park cleared me out and engineered the win for one of the newbies.
Yep, Dawn of Champions (I think that's the name). Some cool stuff, depending on what you think of the previous expansions. If you think things have been getting more and more random to the point that it's unplayable, then this ups that even further.
If you don't mind all of that, then it's a fun expansion.
