maybe you could

- 1 Polymerization
+ 1 Limiter Removal

LOL, Jar of Greed is a Trap card, not a Spell......LOL...................also, where did you get the English card text for these cards? The spoiler has somethig different.

To save room, you could just go the metamorphosis way. Maybe like:

-2 Cyber Dragon
-3 Poly
-1 Dust/Sak. Armor

+1 Ancient Gear Golem/Dark Magician of Chaos
+1 Machine Monster (Mecha Chaser, Cannon Soldier, X Head etc.)
+2 Limiter Removal
+2 Metamorphosis

Or something like that anyways. Unless you REALLY wanna go the Poly way. Without a Lv. 10 Monster, you can't get Cyber End out with Metas... so whatever. Nice deck though.
