Yeah... it would be nice. Not exactly an evolution, but more of a fusion.. thing <.>
Aww yessness. I like a few Poison types and I wish they would get a bit more of light. All I see are the water type Pokemon growing. I mean the water based gets more Pokemon >.>
I think the poison types should get a new weather (acid rain makes the most sense). Also I think they need to have their 'not very effective' and 'super effective' match ups re-evaluated.
