I just beat Lines in the Sand, aka the Masochism chapter.

This chapter had some really annoying fights, including Colossus and War Machine. I’d like to thank everyone who gave tips and tricks for masochism and the colossus fight.
My team:
2/35 Sabretooth (carried in the early fights)
1/7 Black Panther
5/50 Hyperion
4/55 Quake
4/40 Sentinel (carried as well)
I went the Yellowjacket Deadpool path, and Sabretooth really helped there. His synergy with Black Panther let me parry and inflict debuffs. Quake also helped in some fights as well.
But Sentinel man, is freakin awesome. I was debating taking up to r5, and I think I might. That Loki fight before the Storm boss, the Colossus, and of course the caltrops Storm boss. His armor up, heal block, and the regen for survivability.
I played the final fight perfectly, and got full analysis charges almost instantly.

It took me some units, but it is done. I’ll wait on bane for a bit, see how it works.
Once again, thanks for all the tips!
