When Get Excited is countered by Windwall, does the discard still happen?

Ruling: When Get Excited is countered by Windwall, the discard does not happen because the discard is part of the spell's resolution, not a cost.

Nuances:

• If discard were a cost, it would happen before the spell could be countered
• Since discard is part of resolution, a countered spell does not resolve and therefore the discard does not occur
