They practically have the stat base? what do you mean?

---

He means Base Stats. They elaborate how high a Pokemon's stat can go with maxed EVs and IVs and a stat increasing Nature. Also how low with no EVs in the stat, no IVs and a stat decreasing Nature. So he is saying that in total Unfezant ans Swanna have very alike total Base Stats.

Answer 1

Swanna, because it can act as a HM Slave with Fly, Surf, and Dive.
