The key to maximum damage on an opponent dragon is its primary element (the first element). Choose your dragon to have its primary element immune or resistant to the opponent dragon's elements, and your dragon's secondary element supplying attacks that are critical to the opponent's primary element.

A dragon's Secondary Element has no effect on battle damage. Secondary(/Tertiary) Elements enable a Dragon to have alternate attacks. This is why Rare Hybrids are valuable in battles -- they allow the Rare Hybrid to be immune to an Element and to be able to deliver critical damage at the same time.
