1.Stats: Should Swanna get a stat boost, Evolution, Mega Evolution or nothing?
As a mid-game Pokémon that reduced to early-game role, Swanna is rather close to another species, Swablu, in both at the level of evolution and in terms of base stats. For a fuller match it would make sense for Swanna to get +20 BST, which will also help it getting either better offenses or a Speed stat higher than 100, and +30 would allow it to get both.
Nonetheless, since Swanna cannot co beyond 503 BST, it would still require an evolution for +37 more base stats, or a Mega Evolution to make it truly useful. But a simpler stat raise will help it being relevant in-game.
2.Should Swanna get more abilities?
Yes. Though Swanna gets three abilities, all of them are terrible without much of a question. Here's some:
- Gale Wings
- No Guard
- Super Luck
- Water Veil
3. Should Swanna get more moves?
Yes, as Swanna's Water-type stats are terribly bad. It desperately needs more variety and Hydro Pump. In addition, it can gain Blizzard as well. Other moves like Acrobatics and Drill Peck would be interesting as well.
Literally any move from any other type would be nice as well, like dancing moves, Grass Knot, Signal Beam, U-turn etc.
4.What additional typing Swanna can have?
Swanna is hilariously limited so the only options would be Ice and Normal.
