In early game only use your Boomerang Blade to deal much damage if you run out of mana Use your Spell Shield to get mana and continue attacking.
is easy to get mana if you are vs a caster like Karthus or Malzahar

Youmuu's Ghostblade yoummus is a great choice for sivir because you can active and use your On The Hunt to get a better attack speed

In teamfights always have active your Ricochet and always be using your Spell Shield to block some of the enemy attacks or stuns.
