The problem with this? In a word, Mamoswine:
The Swinub family had been blessed with awesome typing since its debut in Gen II. Ground-Type made it immune to Electric attacks and Sandstorm; Ice-Type made it immune to Hail and good against Dragons, which are getting more and more broken as the generations go on. (Seriously, Nintendo, that's a problem). The icy pigs got even more love with the Physical/Special split, an Ice-Type priority move in Gen IV, and an evolution with amazing stats.
Did it really have to look like a huge pile of suck?
There is nothing wrong with making a mammoth Pokemon evolve from a pig. In fact, that's really creative, given the similarity between an elephant's trunk tip and the front of a pig's snout. Mammoths are one of the better-known mammals of the Ice Age, so it even makes sense to have Mamoswine be an Ice Type that requires Ancientpower to evolve.
Mammoths are one of the most well-known prehistoric mammals ever. Unlike, say, a Cynognathus, everybody knows what they looked like. Mamoswine is not a mammoth.
Where's the trunk? Where's the majesty? Mamoswine could have had an awesome design; instead, it looks like...nothing. If only they had made a shaggy elephant just like they made a shaggy pig way back in the G/S/C days.
Oppose Nintendo's half-assed designs. I miss when they actually CARED how Pokemon looked.
