Minion first timer asking for tips

Hi.

This league I decided to try minions for the first time, sounded fun to counter the swarm with a swarm.

My logic was:
- Use glacial cascade with "chance to poison support" to apply virulence and be able to summon the Herald of Agony while having a layer of defense (chill, knockback, freeze).
- Use Volkuur's Guidance to make it easier to poison enemies.
- Have two carrion golems + summon phantasm (on glacial cascade) + herald of purity to buff minion damage while creating a swarm.
- Use Siegebreaker to hopefully create good DoT ground when minions die.
- Maybe add wolves or spiders later on.
- Use Ice Nova of Deep Freeze for when I get surrounded.
- I picked the occultist for the chaos res and freeze immunity (when I have enough res to drop Purity of Elements), but maybe elementalist with CI would be better when I can afford it.

I can clear maps just fine, but it's due to my cold skills. Minions do little.
I don't want to copy a build, just have fun experimenting (this seems like the perfect league to do so), but my question would be: Do you think this can go somewhere or am I hindering myself trying to mix cold with chaos and minions? Would I be better off focusing on chaos skills + HoA? Maybe dropping HoA and just focus on minions + cold?

Thanks in advance.

P.S.: I play with a controller so I'm better off not using anything that requires aim. I already have problems with Frostblink because it doesn't target where I want to go often and sometimes it even makes a weird double-blink making me zig-zag or returning me to my point of origin.
