For getting seiz devices, Go to RTL with 6* spider verse champs and
1. go to Ep 1.1 and keep doing first fight
or
2. go to Ep 1.4 and turn on auto fight for the entire path, keep repeating

Restart game and collect all solo objective milestones from stash.
Match nodes for SQ (They remain constant):
1st fight: Get a mystic to counter the cosmic
2nd fight: Fight or Flight is just fine with any champ. Stay away when unstoppable timer finishes.
3rd fight: Same as previous match with miss as the factor now. Stay away when miss timer finishes.
4th fight: Even with triple debuffs, this match is good one to heal a champ. Maintain good combo meter, you don't need any immunity champ.
5th fight: Bring auto block immune champ or use Herc
6th fight: Bleed based spidey counter like Mole Man or Venom is best
Boss fight: Don't knock boss down. If boss is Soccer Spidey, use Mr Canada or Spidey 2099 else he irritates a lot.
For threat lv5, i m using following team.
I was mostly getting soccer spidey as boss so had to r3 my mr canada because he was the toughest for me.
Here's my team:
