When I first got a Gren Maju De Eiza, I didn't 
think it could be any good. I've only been dueling for about a month now and I'm 
still learning. However last week when I was card shopping I was lucky enough to 
get a Skull Lair in one of the booster packs. Now in case you don't know 
already, Skull Lair is an infinite trap card. It's effect allows you to remove 
any number of cards in your graveyard from play in order to destroy 1 face-up 
monster on the field whose level of stars are equal to the number of cards you 
removed from play. Gren Maju De Eiza's attack and defense becomes the number of 
cards removed from play x 400. That shuld explain it well enough. I didn't know 
how good it was until I dueled a friend, I used Skull Lair to get rid of his 
Blue Eyes which is 8 stars. Then Just a few turns later, a couple others 
totaling my number of cards removed from play to 18. He was winning 5300 life 
points to my 1700, but then I drew Gren Maju and well his attack was 7200. I 
easily beat him after that. So yea, I don't know how good of a combo this really 
is, but it's worked for me thus 
far.
