Masterful Dancer of Chaos

Partner with Ruler of Flames Unbound.
As Masterful Dancer of Chaos enters the battlefield, choose 2, 3, or 4 at random. Masterful Dancer of Chaos has protection from each
converted a cost other than the chosen number.
At the beginning of combat on your turn, if you
both own and control Masterful Dancer of Chaos
and a creature named Ruler of Flames Unbound,
exile them, then meld them into Master Dancer
of Chaotic Flame.
