I've gotten to the point where I am grinding against Landenel... and good god this is an awful, AWFUL MGP sponge.
Random, but he always has Odin... which is an excellent card against random because it has an 8 on 3 sides, making it extremely versatile, which is king in a random match.
On top of Odin, he always has Ifrit or Titan and usually has Bahamut. So multiple 7 sided cards, Bahamut w/ 2 9's, and Odin w/ 3 8's...
Honestly his deck would be bad enough without a random rule. He's about as strong as King and Rowena, but makes you suck.
