So actually, I was thinking to name this thread like "My concern for Deathless Thanos", but this title is wider.
With that said...
I was so psyched to see in the livestream that Deathless Thanos WIELDS STONES!!! (Like Nameless Thanos) cuz honestly I thought they'd base him off regular Thanos, not Nameless.

So we have seen he have Furies, Energize, Panic, Corrusion debuffs...
But I'm concerned his kit won't at all reflect the fact he's wielding infinity stones...
Check out this concept that Gabriel Frizzera shared in Twitter:

So the Evolution stone accelerates natural processes, creates monsters (we won't see that, unless it's the Deathless champs?) And can give unusual abilities to others, how do you think it'll be reflected/how do you want to see it reflected? Imo-a pre fight centered around that stone, that can grant the next champ 1 of 3 effects.
Next: Genesis stone:
This one breaks the barrier between consious and subconscious, what's in your mind can be drawn out to the real world. How do you think it'll be reflected, or how would you like to see it reflected?
Then the Death stone, as you can see there's no clear description as to its power, but we will probably see a cheat death mechanic, both for Deathless Thanos, and Deathless champs through a synergy. I'd also really like to see a pre fight ability like Apoc, where essentially Thanos grants one Deathless champ the Death stone for the reminder of the quest! Imagine a Deathless champion using the very source of its creation and power, and having control over Death! So a pre fight that grants 1 Deathless champ a Death stone passive with lots of benefits (as well as... hear me out... instantly converting any Death immunity triggered by anyone, into instant damage) and one disadvantage to it can be Thanos losing his Death stone and hench no cheat Death mechanic neither to him nor the Deathless champs who doesn't have the pre fight.
Your turn, what do you wanna see in his kit?
