Staff Clones, Winds of Chaos, and Deceptive Evasion
Deceptive Evasion clones use the #1 attack exactly as Staff #2 attack does (if I’m not mistaken)
Bleeds stack from any source, so Sharper Images and Staff bleeds will in fact stack.
Deceptive Evasion creates clones based on your 2h/MH weapon and they will use the appropriate Weapon 1 skill. So yes, all staff clones, regardless if they’re from Staff 2, mirror images, Deceptive Evasion, etc. will cast Staff 1.
Scepter clones do in fact cast Ether bolt. They do not cast the full Scepter 1 chain and as such, never cast Ether Blast (that I can tell, not that it matters) or Ether Clone.
Likewise, Sharper Images does stack so if a clone crits, it will apply the bleed on top of the conditions applied by their weapon (swords = vulnerability, staff = WoC)
Do note that they do not benefit from Illusionary Elasticity or Condition Duration and potentially other traits/attributes so their conditions are easier to push off in a DE.
