When Aphelios (Exalted) has Svellsongur attached, does he get two separate instances of his ability? Can he choose the same effect for both instances? Does Svellsongur see itself being attached for Aphelios's copy effect?

Ruling: When equipment is attached to Aphelios, he gains a copy of his ability from the equipment's effect being appended to his text. Each instance of the ability has its own "choose one that hasn't been chosen" restriction, but these restrictions don't interact - you can choose the same option for different instances within a turn. Svellsongur does not see itself being attached in time to trigger Aphelios's copy effect due to the "as you attach" timing.

Sequence:

• When you attach equipment to Aphelios, the equipment's effect is appended to his rule text
• This creates a copy of Aphelios's ability
• Each instance of the ability resolves independently
• You can choose the same effect for both instances (e.g., ready 4 runes total by choosing "ready 2 runes" twice)

Nuances:

• Svellsongur's "as you attach this" timing means it doesn't copy Aphelios's ability in time for that copy to see Svellsongur being attached
• Each copy of the ability has its own separate "once per turn" restriction that doesn't interfere with other copies
• Subsequent equipment attached after Svellsongur will trigger both the original Aphelios ability and the copy from Svellsongur
