Does attaching Svellsongur to Mindsplitter replay Mindsplitter's ability?

Ruling: No, attaching Svellsongur to Mindsplitter does not replay Mindsplitter's ability. Svellsongur grants a copy of the ability text but does not trigger "when you play" effects.

Nuances:

• Mindsplitter's ability only triggers when you play Mindsplitter from your hand
• Svellsongur copies the ability text itself, not the trigger condition
