Because songs have won this thing on previous occasions.

I want my team to win the war
No team ever haaaaaas
To lose is what we abhor
But we love fame and all the jaaaaaaaazz

We will travel across the site
Competing far and wiiiiiiiiide
Each en-ter-reeeeee to understand
The creativity that's insiiiiiiiiiiiide!

Pokemon! (Crossroads!)
It's you guys and me-ee!
We know it's our destiny!
Pokemon! (Crossroads!)
We're all friends
On a site we will upend(in the ensuing chaos)
Pokemon! (Crossroads!)
A challenge we must do-oo-oo-oo-oo!
Our bad puns will pull us through!
You take this so I don't have to!
Pokemon! (Crossroads!)

Every event along the streak
With courage someone else will (probably) face
We'll all battle every week
And claim our rightful place!
Come, Prism League, the time is right
There's no better team
Arm in arm we'll win the fight
For three weeks it's been our dream!

Pokemon! (Crossroads!)
It's you guys and me-ee!
We know it's our destiny!
Pokemon! (Crossroads!)
We're all friends
On a site we will upend(in the ensuing chaos)
Pokemon! (Crossroads!)
A challenge we must do-oo-oo-oo-oo!
Our bad puns will pull us through!
You take this so I don't have to!
Pokay! Mon Cross! Roooaaaaaads!

Gotta win the war!
Gotta win the waaaaaaaaaaar!
Pokemon! (Crossroads!)

...I tried.
