Hello i hope i am not pretentious with this title xD
It is easy to do, be sure to have a stardust dragon, a red eyes darkness metal dragon, a majestic dragon in grave or hand, and a level eater in grave.

Use red-eyes to summon majestic, then red-eyes -1 to summon eater, tune to majestic star dragon, at the end of turn, stardust returns, and you can at your next turn, spe majestic dragon by red - eyes and spe level eater by red-eyes -1 and do that again and again ^^
Here is a screenshot of my red-eyes Majestic dragon deck ^^

Is that epic ?

Looks like chet.

You Mean cheat? O_O

So i summon 2 alexandrite to queen , and i summoned red eyes by lavalval chain, i summoned savior , use storm and my road to summon stardust, and finally queen's eff to summon other dust and then i used skill drain ^^

Isn't really that complex of a loop, easy to accomplish ._.

But still, Gantz got skills.

A loop can be easy to play, and i think, a easy loop is more powerful, because of lot of dead draws in "hard" loops, here i just have to play one for one and few cards ^^
