5.4.6 ultron boss.. easiest counters

I’m going for 100% of act 5, I don’t remember this fight being so infuriating!
I used medusa earlier but barely got him below 50% with a whole bunch of units used so stopped trying as was wasting so much.
What are the easiest and quickest champs/strategy’s for a lower skilled player like myself to use?
Any advice is much appreciated.. thanks.

    Loki. I beat ultron with a 3*. So 4 or 5* should be easier

    Once you get armour shattered on him with Medusa, the fight is pretty much in the bag. Try to one-shot each time else you will be starting from the beginning

    Magneto pretty easy even a 3* can get him down. Parry heavy sp3, just avoid powergain buff for safety.

    You can also use white mags but it’s slower as he doesn’t hit as hard. Use white mags prefight also to help other champs on your team not trigger his debuffs as your parry stun is passive.

    I explored it back in the day with void before those options existed playing it slow and letting him kill himself with regen.

    On recent mini acc runs I used both magnetos, 3* red and low rank 4* white. Took a revive or two each time due to block damage so if you have maxed out 4* or 5*s maybe boost up you can one shot pretty easy I think.

    Loki, Mags, Medusa

    Void Loki Magneto Medusa are all phenomenal. CAIW can do it in zero hits although it can get dicey if he gets the power gain a lot.

    Loki is cheat code.
    Nebula if you can exile her shock charge.
    CAIW is safe and easy choice.
    Magneto is new cheat code after buff.

    Medusa, duped and with BB synergy
    . End of the discussion.

    As others have said, Mags, medusa, Loki are all good options

    I didnt have any of those for my mini and i just powered it down with Corvus, didnt usually need more than 1-2 revives per run. And i had farmed them specifically for that very annoying fight

    Medusa is the best and most reliable option.

    Mags is probably the quickest and most fun.

    No one has mentioned this but ghost is a really good counter. You don’t trigger any of the things from debuffs and you counter his evade.

    I just put a 4* and 3* loki on my team and didn't even have to use the 4*.

    Magneto is 109x easier than anyone.....even loki

    The one counter I used was the mephisto super team with symbiote supreme, morningstar, ghost rider, and the champion.

    As long as you have morningstar, you start the fight with soul imprisonment and have an extra soul so can hit him with it again.

    That's 30 seconds of not havin to worry about anythin. With my powered up mephisto and bein fully boosted, he melted. An unawakened one fully boosted shouldn't take more than a couple of revives.
