Alright,

Swablu, start off with Haze near the Christmas, release only a little amount that can fade away faster than usual. Wartortletwo, use Substitude while you're under the cover of Haze, the Subtitude should look like Santa. When the Haze fades away, which should be quick, Swablu, use Toxic against the Substitude. Wartortletwo, quickly jump out of the christmas tree, dressed up as an elf, and protect Santa by using Protect.

We saved Christmas
