If I cast a craterhoof behemoth and a Humility is on the battlefield. Would Craterhoof ability fizzle because it enters as a 1/1 no abilities or would my 1/1 creatures get +x/+x?
The ability wouldn't fizzle, because it wouldn't trigger in the first place. The Behemoth just doesn't have any abilities that can trigger when Humility is on the battlefield. It's just another 1/1 dude without abilities entering the battlefield. There is no point in time when the Behemoth is on the battlefield and still has its abilities, it enters already without them.
