Tips on how to deal with perfect comps and wombo-combo

Hey everyone.

Monkey D wukong here saluting you. So i am just your average gold league player seeking some help and clarification on how to deal with great enemy comps in ranked.

What i mean is, sometime the enemy team just has that perfect ult combo that can shred our team easy peasy. I don't know how to deal with them :/

For example: Enemy team has:

out team had:

I was:

both top and mid ( me ) had problems at the begining but we eventually carried our weight. We dealt a bunch of dmg however I simply could not carry my team to y -sadface-

Sej would ult, then annie ult then mf ults and we are over. I know you might say "don't get caught" but even if i try my best not to get caught someone in my team will eventually get caught by blitz hook or a 3 person sej-stun

What i am asking for here is, what do i do in this scenario? do I just fight it out and try to delete the carries still? do i pick a splitpusher champ (if so please provide examples! Or do i no splitpush? because 5v4 vs that comp is just too op? I crieritime the enemy team has a wombo-combo... eritime.
