This is my current main roster, im at 5.2.6 rn and would like to aim for Uncollected next week.

GR is going 5/50, and i can take another 4* to r4 or 5* to r2 if needed.
I have several questions:
1. Will a stash of 20 single revives and 5 team revives, with about 1200 units be enough? (only for revives)
2. What's your recommended team for 5.2.6, but most importantly the Collector?
(My current plan is a Hulk + Void synergy is a must in my team)
3. Will iceman, gwenpool or KM (sp2) be able to survive Collector'sp?
Thanks.
