[GAMEPLAY] Pantheon Aegis blocking TF gold card stun

I was playing on Twisted treeline the other day and the TF on our team threw a gold card at the enemy Pantheon. The pantheon took no damage from the attack and was also not stunned. Pantheon was also blocking the magic damage and slow from Kha' Zix auto attacks. It occurred every time he had his shield up and an auto attack based cc landed on him.
