Hmm, Amoonguss for me. I've been battlign a few Amoonguss's these days & it's been toying around with me. With Spore & everything, it's definitely one of my picks now.
Alomomola has it's focus on HP & it's other stats are not too great, just like Synerjee said, defeating it's purpose. It's movepool is of no use to me too so meh.
My vote goes to Amoonguss .
