Mint (woo!) with an entirety of TWO scions defeated, 7 heroes lost, and 3 environments go boom, with beating down Voss after OblivAeon.
Being OblivAeon, games are going to be very different, so the usual advice goes here. Regular Tempest has a great incap ability of immunity to a damage type so you can avoid the environmental destruction damage. Legacy is great for Heroic Interception or Take Down during phase 3. Give someone like CR, Benchmark, or Stuntman lots of damage increases and power uses/card plays. Complete objectives to flip the shield, then big damage (or WWII Bunker’s power works well) to destroy it.
Personally, I got Lifeline the Apex of Humanity (lol), followed eventually by the Primordial Boon, so he was doing pretty well until OA switched zones and blew up the one he was in. Oops. I switched him with Chrono-Ranger, who really likes the extra damage.
A couple of weird plays etc meant that phase 2 built up more tokens than I would like with OA switching zones at inopportune times, so by the time we went phase 3 all 3 environments were gone. However, at this point CR had Apex, Boon, By Any Means, Ultimate Target, Base Legacy Galvanize, Inspiring Presence, AND Hunter and Hunted. So each card play or power use was doing upwards of 8 damage. From the end of Phase 2, through Phase 3, and through Voss, pretty much every turn was spent using an incap ability to feed CR plays or draws, which blitzed through Phase 3 and Voss within 1 round.
