When you play a creature it's counted as a spell so if that creature has a trigger ability does it apply to the hexproof? (Example: 4/2 hexproof unblockable and a 1/1 elvish mystic, enemy swings a 6/6 with the ability "when ever this creature deals damage, deal 6 damage to all enemies creatures" would it affect the hexproof with the 6 damage ability?
