Played this at the Block, with ongoing destruction destroying either equip or ongoing (although I really like the idea of no environment and enviro targetting equip).
We flip at the start, then put the heroes in play order first to last (alternating teams) and the person who puts a hero in play first is the first to play. The order was Legacy-Tempest-Tachyon-Haka-Wraith-Adept-Bunker-Fanatic. (Fanatic last for end of days going off right away)
Legacy got fortitude and next evolution at the start, and drew Lead from the front his first turn. Haka went after wraith and Tach with Taiaha first turn, wraith pulled razor ord. and bunker had flak cannon and G-gun so Argent Adept dropped quickly, he had Temepst play two cards before he died.
AA started boosting lightning damage as Tempest got Lightning storm and sub-wave enducer. Legacy could absorb Tempest or Haka but not both, after a chain lightning and all lightning boosted round Legacy focused on stopping the lightning rather than Haka, and a HoB later Wraith and Tach were at 6 health.
Bunker, Tempest, Haka and Legacy had -1 damage, Wraith had razor, utility belt and stun bolts, Bunker had grenade, Flak, G-Gun and armor (no turret mode the whole game) Tach had synaptic, Fanatic did not have absolution, tempest had the same as above and Haka had Taiaha when the Block dropped Defensive Displacement.
With Legacy able to tank the one shots from Tempest (-3 damage) and Haka with an empty hand there was almost no damage being done. Tach got her hand up, Fanatic got consecrated ground and Tempest got Ball lightning. Tempest kills Lead from the front and synaptic following Legacy's turn, then Haka Rampages and Taiaha, dropping Tach and Wraith to 3 health. Wraith stealths and Tach puts out a second Synaptic (she had nothing else to play) Fanatic plays consecrated ground, destroying the bubble (2 prison breaks had all five inmates out), eating Wraiths shield and dropping Tach to one health, whe then attacked wraith putting them both at one health for the environment turn, where Char killed both of them.
With boosts from Wraith (destroying ongoing) and Tach and a new Lead from the front Legacy and Bunker drop Fanatic the rest of the way (she was the only person taking damage when the bubble was out) and nearly pulled off the comeback, but Tempest drew reclaim, Fanatic let him play it to get ball lightning back, which he destroyed lead from the front and bunkers armor, then Haka played punish the weak and with Argent giving him a second power Bunker was dead. Legacy held on for three turns with all the help he was getting (cards from trash to hand and play really helped) but in the end he could only negate one type of damage and Tempest got a second inducer, played in on fanatic's turn (so wraith couldn't destroy it) and lightning slash ended it.
It was a great match, closer than I expected, but Tempest and Haka got their reduction and damage, so there wasn't much hope for the F4. Haka ended with 19hp, Tempest with 5. If Legacy had lasted one more turn Tempest would have died and Legacy probably would have beaten Haka. By probably I mean only the Environment deck could have killed him at that point.
Legacy was a beast to deal with, and he only raised damage twice. The damage was heavily favoring Wardens, but Legacy tanking was really rough for them to deal with. In the end it was Ball lightning that won the game, even if it was limited to only ongoing the result probably would have been the same, although if it was enough to get Tempest down before Legacy the fight would have reversed. with eight heroes it was a long fight, nearly two hours.
