Rona, Disciple of Gix

A card, spell, or permanent is historic if it has the legendary supertype, the artifact card type, or the Saga subtype. Having two of those qualities doesn't make an object more historic than another or provide an additional bonus—an object either is historic or it isn't.

Once you begin to cast a card, losing control of Rona won't affect the spell.

You'll still pay all costs for that spell, including additional costs. You may also pay alternative costs such as that granted by Jodah, Archmage Eternal.

The exiled cards aren't in your hand, so you can't cycle them, discard them, or activate any of their activated abilities.

After Rona's last ability resolves, you have priority if it's your turn. You can cast the exiled card before any player can take other actions if it's legal to do so.

You must follow the normal timing permissions and restrictions of the cards you cast from exile.
