Tibalt, the Frog-Blooded

The chorus frogs in the big lagoon
Would sing their songs to the silvery moon.
Tenor singers were out of place,
For every frog was a double bass.
But Tibalt he sang in his high voice mocking
The basses until he started Planeswalking.
And though he is not a powerhouse,
He's got two power - that's more than a mouse.
