1.Stats: Should Torterra get a stat boost, Evolution, Mega Evolution or nothing?

Torterra can get a side evo, but it would mostly prefer a Mega. Its stat distribution is outdated, so it would like a better one.

2.Should Torterra get more abilities?

Yes. Chlorophyll, Sheer Force, Sand Force are all options.

3.Should Torterra get more moves?

Moves like Power Trip, Zen Headbutt, Head Smash, Psychic Fangs, Gunk Shot, and Barrier should be options. Shell Smash would also be good.

4.What additional typing Chesnaught can have?

Dark, Fighting, Steel and Rock are the obvious options.

How to improve: 650-651-652: Chespin-Quilladin-Chesnaught

1.Stats: Should Chesnaught get a stat boost, Evolution, Mega Evolution or nothing?
Chesnaught can get at most +10 BST.

Special side evo would be interesting. But a Mega is necessary for Chesnaught to have any relevance.

2.Should Chesnaught get more abilities?
Yes. Abilities like Iron Fist, Chlorophyll, Leaf Guard, Defiant and Sheer Force are options for Chesnaught.

3.Should Chesnaught get more moves?
Chesnaught needs more Dark-type moves like Assurance and Power Trip, more Electric-type moves like Wild Charge, more Fighting-type moves like Close Combat and more Rock-type moves like Head Smash. Moves like Comet Punch and Force Palm would also be fun. Gunk Shot would also be useful, so would some Fang moves.

4.What additional typing Chesnaught can have?
Rock, Dark, Ground and Steel are options. Electric and Poison are also options.

How to improve: 218-219: Slugma-Magcargo

1.Stats: Should Magcargo get a stat boost, Evolution, Mega Evolution or nothing?

In its most basic form, Magcargo is irredeemable. It is one of the worst species in the game and serves no purpose but to hatch eggs, even then Talonflame is better.

Magcargo needs a Fire/Steel evolution. Anything else is simply a distraction. Even though it got +20 BST update in Gen 7, it still has +110 BST to go.

2.Should Magcargo get more abilities?

Desolate Land or even Drought can work. Sand Stream and Sand Force are also options.

3.Should Magcargo get more moves?

Yes. Magcargo needs Power Gem a lot, but outside of that it needs a whole movepool overhaul. Moves like Sludge Bomb, Sludge Wave, Acid Spray, Flash Cannon, Nasty Plot, Shadow Ball etc. can all help.

4.What additional typing Magcargo can have?

Ground, Steel are major options. Bug and Poison are lesser options.

How to improve: 707: Klefki

1.Stats: Should Klefki get a stat boost, Evolution, Mega Evolution or nothing?

Yes. Klefki has very low BST, and no stats that reach above 100. It can get at most +70 BST, but a smaller boost is sufficient.

Klefki definitely deserves an evolution and a pre-evolution. A Mega should only be considered as a last resort.

2.Should Klefki get more abilities?

Yes. Misty Surge is the most obvious option, but stuff like Magic Guard, Trace, Levitate, Synchronize, Clear Body are all options as well.

3. Should Klefki get more moves?

Yes, moves like Magnet Bomb, Beat Up, Stored Power, Nasty Plot, Cosmic Power should all be available for Klefki. Klefki would also enjoy moves like Simple Beam.

4.What additional typing Klefki can have?

Dark, Psychic and Ghost are obvious options. Electric and Flying are also options.

How to improve: 396-397-398: Starly-Staravia-Staraptor

1.Stats: Should Staraptor get a stat boost, Evolution, Mega Evolution or nothing?

At maximum Staraptor can get +55 BST boost. But 10-15 is more likely.

Staraptor cannot evolve further, but a side evolution would be great. Could be faster or specially oriented.

Staraptor definitely deserves a Mega.

2.Should Staraptor get more abilities?

Yes. Staraptor only has two abilities. Defiant, Sheer Force, Gale Wings and Big Pecks are options.

3.Should Staraptor get more moves?

Yes. Dark-type moves like Beat Up, Assurance, Flying moves like Acrobatics, Fighting moves like Superpower and Bulk Up, Normal-type moves like Swords Dance and perhaps some other moves like Psycho Cut can work.

4.What additional typing Staraptor can have?

Dark and Fighting are obvious ones, but Steel and Ground can work as well.
