I know what your thinking: Mask of restrict? in a lv5 + monster deck? what is he thinking? You'll see.

Monsters (17):
Dark Ruler Hades x2,
Horus Lv6 x2,
Cyber Dragon x3,
Swift Gaia x2,
Nimble Momonga x3,
Airknight x2,
Cat of ill omen,
Different Dimension Dragon x2,

Spells:
Reasoning x3,
Cost down x3,
Premature Burial,
Card Destruction,
Heavy Storm,
NoX,
Snatch Steal,
Reload x2,
MST,
Dark Hole,

Traps (8):
Mask of Restrict x3,
Level Conversion Lab. x3,
A Hero Emerges x2,

what if you dont draw Cost Down soon enough? you have no way of searching for it and if you dont get it early in the game then your pretty much screwed with all those trib monsters and only a few 4 or lower. :ermm:

maybe add something that can search for Cost Down better? like Different Dimension Capsule? or you could add some more swarm monsters like Giant Germ just incase you dont get Cost Down fast.

i know i probley wasnt much help, but if you could please R/F my deck ^^

lol, your right, looking over this deck it dosnt have as much tribute special summoning as i thought it did when i made it...hmm, will look for something to help with that.
