Help with SSF SRS

Hi, i've been playing SRS on SSF for a long time, but i can never have a descent end game, i always struggle on red maps of all tiers. I've tried following a few guide but i don't know what i'm doing wrong or is because all the SRS guides are readapted versions of old guides.

So i'm here asking for help, to see what i can improve and try to find what i'm doing wrong.

BUILD IDEIA: I just want to play SRS as my main skill not depending on other minions like zombies or spectres.
