Raul, Trouble Shooter

You must pay the costs to cast that spell. If it has an alternative cost, you may cast it for that cost instead.

If you cast a spell from among cards in your graveyard that were milled this turn using another permission, Raul’s effect doesn’t apply. You can cast another spell among cards in your graveyard that were milled this turn using the permission granted by Raul’s first ability.

Once you begin to cast the spell, losing control of Raul won’t affect the spell.
