If Lee Sin is copied by Svellsongur, can you exhaust him once to trigger both copies of his exhaust ability and get double the buff?

Ruling: No, you cannot double up on Lee Sin's exhaust ability when copied by Svellsongur. Since both copies of the ability require exhausting Lee Sin as a cost, and you can only exhaust him once, you can only activate one of the two abilities.

Nuances:

• Svellsongur gives Lee Sin a second copy of his text, meaning he has two separate abilities that both require exhausting as a cost
• This makes the copy essentially a waste for Lee Sin's exhaust ability
• However, if Lee Sin is orange (upgraded), the copied aura effect (+4 Might) would still provide value
