Summoned Beast. The Winged Dragon of Ra cannot exist in the natural world and can only be summoned by a 20th Monster Duelist using the Duel Disk Mk II

Chant of Release: When summoned the winged dragon is contained within an orb of light that can only be opened by reciting the ancient words: "Great beast of the sky, please hear my cry. Transform thyself from orb of light and bring me victory in this fight. Envelop the desert with your glow and cast your rage upon my foe. Unlock your powers from deep within so that together we may win. Appear in this Shadow Game as I call out your name WINGED DRAGON OF RA!!!" Upon speaking these words the winged dragon bursts from the orb in all of it's golden glory

Sacrificial Power. Ra's may give up their spell slots to increase his power. Ra's power, or X, is equal to the total level count of all the spell slots sacrificed combined (For example if you were to give up a 9th level slot, a 5th level slot, and a 2nd level slot, X would equal 15) cantrips cannot be offered as they are effectively 0th level spells.

Light of the Sun: Whenever Ra is present, the effects of the spell Daylight are active everywhere in a 300 ft radius

 Sun Flare Blast. Ranged Attack: +10 to hit, range 200/200 ft., 1 target. Hit: Xd12 + 5 fire damage.

The Winged Dragon of Ra can enter Phoenix Form once every day

Phoenix Form. Ra transforms into his phoenix form, dealing Xd20 damage to all enemies in the combat.
