I need a ruling on Aminato's blink effect. My friend believes that because it states any permanent that you own, then regardless of where the card currently is whether it is in the graveyard or exile you should be able to Target it and then return it to play. Turning it from a blink to a return to the battlefield from the graveyard effect . I explained to him, that a permanent is a creature, artifact, land, enchantment, or planeswalker that is on the battlefield. But the second it leaves the battlefield is no longer a legal Target as it is a card in your graveyard or exile. As if that were true then that would mean I could blink cards from Exile back into play as well. Thus I need a proper ruling from someone who knows a bit more than me.
110.1. A permanent is a card or token on the battlefield. A permanent remains on the battlefield indefinitely. A card or token becomes a permanent as it enters the battlefield and it stops being a permanent as it's moved to another zone by an effect or rule.
