Gauntlet finale help w/ 3* only

Need some help/advice guys as I’m only using 3* characters
for beating first QS node (Fist, hood, hulkbuster),
and for the final node Situation 42 (Ultron Prime, x-force, 4* deadpool) using only 3*
Thanks in advance

If you check the event thread here you’ll find lots of ideas.

That being said, I used LCap, SWitch and Hood 42 and won pretty easily.

QS node I used QS, LCap and Deadpool, though I’m pretty sure I used whales haha.
