Hmm... Good idea. Aipom needs an evolution with better stats. Maybe make it Normal/dark because aipom is normal. new type combos are needed to mix things up.
How about a fire/dragon type with levitate? It would make a really good fire type (most are hard to battle competitively with in the games). Water would do normal damage and those hated earthquakes would do no damage! XD
Ermm, are you talking about cards?
