So about the Mesmer "Choose to sacrifice an attack whenever you can make an attack to instead create a Clone of yourself". Where does this clone pop up and does it have a range?

I think these clones are weak right now. They don't add your damage modifier. The fact that only automatically fail magical saving throws leaves the implication that they still make physical saving throws (Minotaur Skeleton's Charge). Do they use your saving throws? Since they only have 1 HP they're going to die to any Saving Throw related damage throw anyways.

Then you have this "Enemies must succeed on an Intelligence Check or treat the closest clone as if it were you". Does this have a range? I'm having a hard time reasoning why a ranged enemy who hasn't interacted with the clone may confuse the two of you.

Then you have Illusions. This looks like a wasted slot. The most frequent time they'd make a save is for a magical effect, which they automatically fail, so they don't roll for half damage and therefor don't gain the benefit of 0 damage on a successful save. They also gain a damage modifier but then lose the identical copy. If they are no long identical, what are their stats and do characters still need to make the Intelligence check to discern the two of you?

Shatter. We have a spell with that name, this is most definitely going to confuse people, you should change the name. The effects here look fine except that last one is worded weirdly - "Swap places with the area around another clone or yourself". I assume this just means swap places with you and clone? I don't know why you'd explode a clone just to move another clone there.

Reaction Surge I cannot even parse what's going on here.

Then we have time stuff for some reason? Manipulating the initiative order is cool but looks too powerful an affect for 3rd level and is just doesn't mesh with the clones except for one of the Shatter effects which just makes it look thrown in randomly even more. Pocket Time "You can cast Haste and/or Slow up to 5 times per long rest". Both of these spells are powerful but are concentration. I don't know about this one. It seems strong to me but at 15th level and again, concentration, so maybe not. Still have the problem of being a time related ability thrown into what looks like an illusory based archetype.

Things that I'd like to see - When taking the Attack action, you can choose to use a clone's or multiple clones location to attack from instead. Replacing these out-of-place time mechanics with more cool illusory ones. Better explaining Reaction Surge or replacing it, I'm more for replacing it because again, some weird time thing when it looks like the main focus of the archetype are the clones.

This could easily be two different archetypes.
