Technical rules distinction:
Surrak Dragonclaw doesn't prevent your creature spells from being targeted by counterspells, it just means the counter spell doesn't have any effect on your spell when it resolves (for example, if your opponent uses
Remand on one of your creature spells while you control Surrak, the
Remand will resolve and your opponent will draw a card, but it will have no effect on your creature spell, which then resolves.)
