As you really need to learn the mechanics, you should start with a build that let you make a lot of mistakes so you can see what does high damage and what not.

HOW TO:
Focus on being immortal, you can kill him in literally 1ex budget, maybe even less.
Damage will be terrible but at least it will teach you how to do the fight.

I kill him in the first 3 days of the league in 100c budget with zero issues, aw8 on 3ex budget within a week at most, always deathless.

Just build a RF, 9 endurance charges. Instead of RF use SR totem, 6linked on your chest. You can also use searing bond or manually cast SR as a chieftain. Kaom rings, all endurance nodes, high life regen. Hell, even use vitality and but vitality watcher's eye.
Have 100% elemental ailments avoidance (anointment, craft on helmet, craft on gloves, craft on armor), 75 CR, at least 3k regen.
10k hp, about 2mi damage. It's really slow but you can literally afk in his storms and facetank everything. You can even facetank his beam after getting maximum stacks from the spinning red thing.

Is this a good build? No. But it lets you learn the fight.
Again: anything with high regen, 75 chaos res, 9-10 endurance charges and 100% ailments avoidance as you probably can't time anti-shock flasks decently.
Cyclone with nebulochs also works easily (as very fucking slow), molten strike, tectonic.. anything jugg/chieftain/endurance based is VERY forgiving on mistakes... you actually have to try REALLY hard to die (the only way my chieftain can die is if I afk on the middle of the red beams without endurance charges, otherwise I ignore all his skills).

20ex budget you can pick maybe 50 different builds to kill him deathless 100% of the time, insta-phasing EVERYTHING.. but that won't improve your skills at all.
