Adding Sphere Kuriboh

Put it on EC. Also, place 2 Element saurus on 2 Urabys. They are so helpful against ladybug, yomi ship and other annoying effect monsters.

You can replace Enemy Controller. Enemy Controller is still really good, but needs to be set to be used in a similar manner as Sphere Kuriboh. Sphere Kuriboh, however, activates from the hand, which is technically safer.

I guess it comes to preference, and there's no right or wrong choice. You want a card that can also take control of an opponent's monster? Or do you want a defensive card that can be activated from the safety of the hand (Divine Wrath and Overwhelm can still counter it, though)?

Personally, I'd say stick with Enemy Controller, since at least you can nab a potentially powerful monster from your opponent, and either OTK them, or sack the monster after its use with Order to Charge (if it's a Blue-Eyes or something).
