1.Stats: Should Mismagius get a stat boost, Evolution, Mega Evolution or nothing?
Mismagius can get +10 BST to match Honchkrow, but it can also get 535 BST, to match Tangrowth.
An evolution can work if it rearranges its stats, as Mismagius' stats are based on Misdreavus' stats.
A Mega without a stat boost would not be good, but a Mega with stat boost can work.
2.Should Mismagius get more abilities?
Yes. Mismagius only has one ability, Levitate. Other options would be:
- Vital Spirit
- Wonder Skin
3.Should Mismagius get more moves?
Generally speaking no. Moonblast and Recover might help, but it doesn't need much more moves. But it can get the following:
- Draining Kiss
- Inferno(Former event-only)
4.What additional typing Mismagius can have?
Fairy, Dark, Psychic, Electric and Grass are the obvious options. Fire can also work.
