When this card is face-up on the field and control shifts to your opponent, inflict 2000 points of direct damage to your opponents LP.  This effect can only be used once as long as this card remains face-up on the field.

            At first these guys were pretty bad. But then CRV gives us a card called Shien's Spy.

Shien's Spy - Normal Spell

Select 1 face-up monster on your side of the field to activate this card.  Until the end phase of this turn, shift control of the selected monster to your opponent.

            Basicly the combo goes like this:

            1. Play Griggle/Ameba

            2. Play Shien's Spy and choose Griggle/Ameba

            3. Switch control of Griggle/Ameba to your opponent to gain 3000 LP or inflict 2000 damage

            Thanks for checking out my combo. I hope it serves you well.
