nah I was doing it on the rooftops.
my team was 2 star widow, 1 star storm and thor
Step 1, I used some boosts to get some AP in my pool a battery going.
step 2, match any 4+ moves i can if none I aim for a red to pair with my boosts to remove the element tiles to have a better chance at more 4+ moves... I want a lot of every color AP so 4+ matches are important... just focusing on 1-2 colors results in the battery dying quick.
step 3, after I collect enough ap I trigger the battery.... on the rooftops it's hard to keep it going forever, thus what my 2 star widow is there for... I use the battery to fuel her purpler and blue moves to steal all of their AP (well minus purple because I only have 3 covers
) and heal myself to full (usually when I start the battery I have less than 1k hp on each character)... usually when the battery dies it's just a match or two away from going off again thus I just need to take those few hits while at full hp again and start all over.
I think I ended up doing 10 or so matches against the last level 230 team in the match that gave you a lot of points (the one whose reward is the large amount of iso) and I only lost once... and that was because one time when the battery died I accidentally made a 5 match on the board for them to take which cascaded into another 5 match using a crit and ended my storm BOOM >.>;
