FIrst of all, you forgot Sparky + Tornado

You tornado troops next to the Princess or King Tower so the Sparky splashes the tower and the troop

Second of all, according to OJ, if you're Rocket and Tornadoing on your opponent's side of the map, cast rocket first and then tornado. If you are Rocket and Tornadoing on your side of the arena, cast Tornado first and Rocket right after. This is due to the Rocket's varying travel times on different parts of the arena in relation to the King Tower.
