Gods Willing

If the target creature is an illegal target by the time Gods Willing tries to resolve, the spell doesn't resolve. You won't scry 1. If the target creature becomes an illegal target while Gods Willing is resolving (most likely because you gave it protection from white), you do scry 1.

You can't choose "artifact" or "colorless" as Gods Willing asks you to choose a color because those are not colors.

You perform the actions stated on a card in sequence. For some spells and abilities, that means you'll scry last. For others, that means you'll scry and then perform other actions.

You choose how to order cards returned to your library after scrying no matter where you put them.

Scry appears on some spells and abilities with one or more targets. If all of the spell or ability's targets are illegal when it tries to resolve, it won't resolve and none of its effects will happen. You won't scry.

You choose the color as Gods Willing resolves. Once the color is chosen, it's too late for players to respond.

When you scry, you may put all the cards you look at back on top of your library, you may put all of those cards on the bottom of your library, or you may put some of those cards on top and the rest of them on the bottom.
