Send your
exodia parts to power boost the
legendary exodia incarnate. The monster is
unaffected by cards effect so a way to activate
Obliterate!!! if the opponent doesn't have card on the field. Else you can use
a cat of Ill Omen to search
Obliterate!!! then send the cat back to your hand with it.
There is
Imperial custom and
Imperial iron wall to protect
Obliterate!!! when you don't need those cards you can use
magic planter on them to draw 2 cards.
At the end the deck is pretty much: move your
exodia cards from deck->graveyard->hand/field->graveyard (be sure to keep a
forbidden one card in your hand to 'protect'
legendary exodia incarnate.
