Deck tips for ranked standard?

I’m currently using the sephiroth “Villains of Darkness” deck

But I also got the Cloud “Warriors Of Light” deck

Sephiroth is arguably my favourite playstyle, and is quite similar to my irl commander deck, but I’m losing HARD in ranked standard, I keep being absolutely destroyed by token lifelink, and cat lifelink decks, and some other deck types but it seems bronze is 90% token/cat deck users.

I think one problem with the deck seems to be the ability to get my synergies on the board without being drained of my hp beforehand
