With the exception of Freedom 5, they were all really close matches. Many teams were able to take advantage of Mordengrad discarding Carrion Fields and Cohorts.
Some highlights:
Nightmist in Mist Form allowing for consequence free bird destruction.
Lifeline coming back from 1 HP to 27 HP as part of a huge upset victory for team Space.
Luminary completely shutting down Carrion Fields with Regression Turret and getting a damage boost from Mobile Alert Platform.
Medico just barely keeping Void Guard alive for basically the entire game.
Visionary putting the Mask and 7 birds under Matriarch's deck and using deck control to get her to play Darken the sky 2 additional times afterward.
Round 43 results: Losses for Prime Wardens and Alt Reality. Wins for all other teams. The Prime Wardens battle was a 2 hour battle, mostly Fanatic 1 on 1 vs. Blade with her surviving due to Aegis 4 separate times before her ultimate defeat.
Round 44: Challenge La Capitan at Champion Studios.
Round 45 Results: Alt Realities losing streak continues, Dark Watch loses as well. All other teams win - though Void Guard did so with only Writhe standing at 1 HP.
Turn 1 Strength of the Grave didn’t help either with 5 instances of 8 damage. What probably did the heroes in were 2 really unlucky Vast Followings which brought out Gloomy’s most dangerous Cultists. Interestingly, Ra played imbued Fire round 1 and relics didn’t enter play until fairly late; which makes me think that had the game been standard difficulty instead of Ultimate Nature would likely still have lost.
Round 47 Results: All teams win. Prime Wardens had the easiest time of it thanks to End of Days; on the other end of the spectrum, Alt. Reality had a brutal fight that ended with all heroes still active at 1 HP each.
Round 48: Challenge Kaagra Warfang at Fort Adamant.
Went about as well as I thought it would, surprised Dark Watch won though, I suspect Expat started with the assualt rifle/shotgun and Setback started with Looking Up.
Actually no, Setback eventually got looking up but it was fairly late in the game. Expat didn’t get a gun out until round 3. NightMist and Harpy picked up the slack though thanks to multiple copies of Oblivion and a high Avian strategy with Huginn and Muninn in play.
