you mean water/ghost, ground/ghost pokemon only evolves once, there are 3 new bug/steel pokemon (doesn't qualify as a slew - a large number or quantity), its dragon/fire and dragon/electric, though there are 4 new dragons (3 dragons are part of an evolution line), they are other pure dragons like dratini, dragonair, bagon and shelgon. They should've made other interesting dragon types like psychic/dragon and bug/dragon (should've been vibrava and flygon - vibrava looks like a mosquito)
