"Elektra: Way of the Stick" reads: While active, your character dice with purchase cost 2 or less cannot be targeted by global abilities (yours or your opponents).
I know that Sidekick dice while in the field are level 1 characters since they only have 1 level and so by default that 1 level is considered level 1. My question is that taking into consideration both the spirit of that ruling and the above game text, are Sidekick dice protected by Elektra while she's active? I would consider sidekick dice in the field as a zero purchase cost since you never have to purchase them, and thus they'd fall under the protection clause of "characters with 2 or less purchase cost."
Is this correct?
