A few good variations are: Surf, Body Slam, Amnesia, Self Destruct
Ice Beam, Thunderbolt, Rest, Amnesia

The first set could do much better with Rest, but Self Destruct can have merits for getting a KO on something none of the other attacks could achieve. The 2nd set is just cool. No explanation needed. 8) You could put Body Slam over Thunderbolt possibly.
