Here's a card whose potential was greatly overlooked by most when the set list for "Rise of Destiny" was originally released, but whose comboability makes him a very powerful monster. He's a 7 Star, 2800/2000 creature. Not that bad for only a 7 Star, though 2 tributes can hurt if you normal summon him that way. His effect however lets you normal summon him without any tribute, though he becomes a 1400/1000 creature. Ok, that could hurt on it's own but let's see how to make this no tribute side of him a complete powerhouse:
Book of Moon: the effect disappears, you have a 2000 defender or after he's flipped back to attack position, a free 2800.
Skill Drain: normal summon him, his effect is negated so he stays 2800/2000
Megamorph: depending on your life points, he'll be no worse than the 1400 he'd be otherwise or a nasty 5600
Metamorphosis: Change him into "St. Joan", "Twin-Headed Thunder Dragon" (both 2800 attackers) or "The Last Warrior from Another Planet" (for some "Last Turn" love).
"Fusilier Dragon" will likely find a home in many deck types because of his flexibility as well as the ease in which you can get a no tribute 2800 beatstick on the field.
