ULTIMATE Battle Arena for Devolution Battle Royale 2!

[Shruikan]

I'll discard Fun Flip so I can buy and use a Dueling Glove to challenge Scytherwolf to fight me.
And I'll also prime the Brass Balls and Cheaty Cookie while I'm at it.

EDIT: I'll also discard the Wishier Piece, and use a Metamorphosis from the item dump to swap my backup lineups.
New Lineups:

Spoiler:

Mew (1)
Mew (1)
Mew (1)
Mew (1)

Then I'll grab the previously discarded Wishier Piece back out of the rubbish pile into my inventory again.
