Creature spells you control with power 5 or greater can't be countered.
"Some think its immunity to countermagic evolved because of the constant mage attacks on Naya. I think it just ate a bunch of wizards." —Broka, drumhunter

If a creature card has “*” in its power, the ability that defines “*” works in all zones, including the stack.

Any spells or abilities that would counter Spellbreaker Behemoth or (once it’s on the battlefield) a creature spell you control with power 5 or greater can still be cast or activated and will still resolve. They just won’t counter that spell. Any other effects they have will happen as normal.
