Some types that I want to see in Generation V...
Steel/Poison - two weaknesses: Ground (4x like the Magnemite family), and Fire (2x, which is common among most steel types)
Electric/Grass - Negates ground, but introduces Fire, Ice and Bug weaknesses
Bug/Psychic... otoh, maybe not... six weaknesses, but it's probably going to happen anyway (in fact, I think the Venonat family should have been Bug/Psychic in the first place. =/)
Psychic/Dark - Despite a 4x Bug weakness, it would be awesome... =P
Electric/Ice - like a refrigerator or something? I've wanted to see this type combo for years...
Normal/Ghost - only one weakness, Dark, but it'll have three immunities... (if you give it Levitate, that makes it four. =P)
Also, Jynx and Farfetch'd need evolutions this time... since Jynx is like a counterpart to Electabuzz and Magmar anyway... and Farfetch'd, well... you get the picture.
