I've said it before, and I'll say it again, but this card has some insanely, mouth watering, visually orgasmic artwork.  Tellarknight Ptolemaeus is a Rank 4, Light attributed XYZ Monster, also a Warrior, with a despicable 550 attack (those as you should be aware 50 in the attack fits the theme) and a very impressive 2600 defense.  XYZ Summoned with two or more Level 4 Monsters.  I wish this guy had an instant win on him...while he does a couple of cool things, it probably isn't enough to be played.  By detaching three XYZ Material from this card, Special Summon a non-number XYZ Monster that is ONE Rank higher from your Extra Deck.  This card becomes XYZ Material for that card, as well as any XYZ Material this card may have.  By detaching seven XYZ Material from this card, you can skip your opponent's next turn.  That's phenomenal.  That's Yata level epic right there.  Just way slower.  Let's say you use three Monsters to XYZ Summon this card (and use the last effect of this card, that's still two turns before you get to skip one of your opponent's, and this guy likely won't be around then) but there are ways to cycle and add XYZ Material.  This guy might actually be better suited for his own Deck as opposed to Tellar/Stellar/etc if you're going for that effect.  You're able to add a Stellarknight card to this as XYZ Material during each players End Phase.  I know this is a lot of work, and a lot of investment, but he's not terribly slow, he can do a few different things, and this is a solid Archtype.
 
Rating (generous as it may be and art influenced a tad):  3/5
Art:  5/5
