I argued for this in the Syclant movepool threads, and I'm going to reiterate them here. Please do not go overboard with the total number of moves on this thing. We are already giving this perfect typing and nice stats. A huge total movepool just looks bad.
I actually like a lot of the variety in the movepool, but I'd like to keep the total number of moves down. When people look at the pokemon and they see a long movelist, they automatically assume it gets "everything in the book" -- even if there is a lot of filler. On this pokemon, if it has stuff like the elemental punches and Power Whip, along with some decent STAB moves -- it better be in a short overall movelist. Otherwise, we are going to be roundly criticized for overdoing it on the movepool.
Here's a few points of reference regarding movepool size:
Syclant got 15 level-up, 51 TM, and 7 egg moves. The level up and egg list is OK, but 51 TMs is huge. The total movepool is 73 moves.
Clefable is commonly known as having a HUGE movepool. It gets 20 level-up, 53 TMs, and 10 egg moves. 83 total moves.
Tyranitar has an insanely large movepool. It gets 18 level-up, 57 TM's and 10 egg moves. A whopping 85 total moves.
Gyarados is known for having a small-but-effective movepool. It gets 14 level-up, 42 TMs, and 0 egg moves. 56 total moves.
Dusknoir has a large movepool. 20 level-up, 48 TMs, and 7 egg moves. 75 total moves.
Hitmonchan is known for having a lot of variety. But, it's movepool is surprisingly small. 19 level up, 32 TMs, and 8 egg moves. 59 total moves.
I have not counted the movepools of every pokemon. I just counted a few examples off the top of my head. But, it does give you somewhat of an idea around the numbers associated with various other pokemon.
I think this pokemon really needs to have a small total movepool. I'm thinking in the range of 60-65 total moves. If we do that, we need to trim a lot of excess out of the current movelist suggestions. But, I think we can do it, and STILL have a lot of variety in the movepool. Look at Hitmonchan's moves if you don't believe me.
But, please don't do like we did with Syclant and give it 50+ TMs. Even though Syclant has a reasonable number of level-up and egg moves, the TM list is huge. And most of those moves are not needed competitively. I'm all for including some "flavor moves" here and there. But, please keep in mind what people think when they look at the move list. Sure, people will notice type coverage. And that's the most important thing competitively. But, if those moves are scattered amongst an enormous list of filler and support moves -- it just begs for criticism. I'd like to see our mummy have a "small but effective" movepool, not an "all but the kitchen sink" movepool.
