Wriri, Flan Princess

Prismatic (This card is all colors at all times.)
Partner with Wiri, the Multitudinous, the Advantageous, the Cantankerous, the Furious, and the Monstrous. They partner with this card and each other.
At the beginning of the end step, if Wiri, the Multitudinous is on the command zone, switch it with this creature and move this card's mana cost to that card.
