Titan, the World's Rebirth

Titan, the World's Rebirth:

Eye of the Titan:

Prophecy of Devastation:

Temple of the Titan:

Titan's Prophet:

Knight of the Titan:

The goal here is to repeatedly bring out Titan, The World's Rebirth using Titan's Prophet and Prophecy of Destruction. As for Titan's own effects, the idea is that he can overpower some really big monsters, but your opponent can still destroy him in battle. As such, he loses a large chunk of ATK and DEF whenever your opponent declares an attack. Because your opponent doesn't take battle damage from attacking it, he could potentially suicide small monsters into him to soften him up before finishing him off. I'm thinking of reducing his ATK/DEF to 3800 though, to make that a more feasible strategy. 3800 is still really big, but even one ATK/DEF reduction means that you can kill him with an 1800+ ATK monster.
