If a unit I kill for the equip cost for Blade of the Ruined King is saved by Soraka, do I still get to equip it?

Question

Accepted Answer

Yes, you still successfully equip *Blade of the Ruined King* if the unit you kill for the cost is saved by *Soraka*.

According to the official ruling in **FAQ #374**:
"Ruling: Yes, you can save the unit with Soraka and it is still considered that you've paid the cost to equip Blade of the Ruined King."

### Why this works:
1.  **Cost Payment:** When you pay the cost to equip *Blade of the Ruined King*, you are instructed to "Kill a friendly unit."
2.  **Replacement Effect:** *Soraka's* ability is a replacement effect. It intercedes during the execution of the kill instruction.
3.  **Rule 354.2.a:** This rule explicitly states: "Costs that are replaced with other events by replacement effects are still considered paid." 
4.  **Outcome:** Because the cost is considered paid, the *Equip* ability proceeds to completion, and the *Blade of the Ruined King* is attached to your chosen target.

Note: I could not fully verify this ruling against the retrieved rules.
