This deck is crazy! I bet you wont stand a chance against parasite deck or a deck with order to charge and enemy controler or even a simple card like twister LOL
waaaaaaay too many monsters, not enough variety in spells. You're not going to get into Platinum with this deck. And honestly Deadalus is not what it used to be. GK's have a better nuke option that DOESN'T clear the whole field and leave you SOL if they've got a kuriboh. Any relinquished deck with kuriboh and fulfillment of the contract will eat this for lunch.
edit: also noticed you're not running a 2nd umi. If they drop twister or de-spell on you, you'll likely end up with 3 deadalus in your hands that you can't summon, and can't field clear.
