***=new edit

There it is,so tell me what you think.r/f will be returned! ;)

use either ..

windstorm of etaqua or zero gravity to abuse Mefist and shadowslayer.

You definitely need...

Zero Gravity
Windstorm of Etaqua
Earthquake
Curse of Anubis
Micro Ray
Ballista of Rampart Smashing (Mefist becomes a 3300 with Inferno Hammer turning mons into f/d DEF)

the above are all great suggestions. i'll just add that mimic lv1 would work out more often since you can get it back with assailant if needed.

IMPORTANT EDIT!

-Bottomless Trap Hole x2
+Ceasefire x1
+Curse of Anubis x1

>>>I am not trying to stop them from summoning,I am trying to switch them to defense.

-The Puppet Magic of Dark Ruler x1
+Ojama Trio x1

>>>Didn't ever once use this card .The only thing it did was give me a heavy hand.

-Smashing Ground x1
+Hammer Shot x1

>>>Like I said before,I am more worried with the high attackers.

-Dark Necrofear x1
+Chiron the Mage x1

I know this deck is mostly fiend but like The Puppet Magic,I didn't bring her out.Don't worry about her,she is side-decked.
