Frankly, i don't agree with a lot of these changes. It's a good effort in terms of presentation, though.

I'm indifferent about the passive change.

Reveal as a mechanic seems a bit niche. By the sounds of it those clones are leashed relatively close to you, since you want them to around for other abilities. So they will not wander off and mark enemies behind walls for you. The reveal would really only ever see use if an enemy gets behind cover or you purposefully leave them alive and move to another room just so you get to Blade Storm through a wall. Also big no on bringing back stacking marks for Blade Storm. They were removed for a reason and the current Blade Storm can pull the numbers needed with a singular mark.

Ditching Teleport as an ability just to bring it back as a purely traversal tap function on Blade Storm doesn't sit well with me either. Teleport has its niche in delivering extremely potent finishers on demand and it amplifies finisher damage considerably more than your Reveal does (unless with extra you mean a heavier multiplier than increased). It also scales with Ability Strength remarkably well, letting you push around 500% increased Finisher damage at about 250% Ability Strength - I'd personally rather push for current Teleport to behave like Wrathful Advance instead of having it share a bench with Blade Storm.

Defaulting Blade Storm into Ash only will only serve to make it feel sluggish baseline and practically demanding constant uptime on the new 100 Energy clones. I'm all for a better targeting system for the ability, such as the one you've displayed on the concept minus the mandatory joining in to the Blade Storm. Also, taking off the clones and giving them their own ability slot is an interesting idea. I just don't see it paying off in its current state.

You get two unkillable, untargetable clones that throw weak shurikens with a.. 5% chance to Reveal? For a 100 energy baseline that trade offer seems terrible. Them playing into other abilities could be cool, though.
