Monster -
Kuriboh/Hane Kuriboh - Always helpful in a tightspot and Hane Kuriboh is a nice little Waboku varient, my PCY Kuriboh is something I will never ever let go.
DMG/Toon DMG - Cute, maybe no great effect but just always a card I've been atatched too, both varients. My first ed DMG is a card very valuable to me for multiple reasons
Magician's Valkyrie - Perfect for the Spellcasters, shame it misses Marauding's 2nd effect though
Spell -
Scapegoat - Again, vury handy and ya cannae go wrong with SHEEP
Enemy Controller - Even better then Change of Heart, quickplay, both defensive and offensive uses.
Diffusion Wave Motion - Makes very good use of high powered Spellcasters, no worries about face down monster effects either
Trap -
Magic Cylinder - Self explainitory, negates the attack, does even more damage to the attacker
Mirror Force - Very handy as everyone knows and a right bitch when its used against ya
Xing Zhen Hu - can make things very frustrating for your opponent when two are used, leaves them with just one s/t zone
