This is the good old troll deck, but still need improvements,

try it and give your comment about this deck and fix if possible,

Nice  not many people use kaiser colosseum which kinda sucks cause it really stops OTK's

 Except hieratic OTK's sometimes cause people use su for that strategy.

yh, this deck has bad defense against effect monster, thats why this deck need improvements,

Have you tried Skill drain? If you do i suggest using malefics, That way you have a decent offense

i have tried skill drain, but it not work well, 
malefics is a nice idea, i will try it.

I suggest using you use skilldrain though, In malefics it stops them from dying from their effects, and it also slows down your opponent.
