How to improve: 347-348: Anorith-Armaldo

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

Armaldo has at best 30 more stats it can get... and it won't help it much. It will help it in-game certainly, but not competitively.

An evolution with great speed would be better and help it differentiate from other Rock/Bug-types.

A Mega can be interesting, but would probably be either part Steel, or just a Golisopod or Mega Aggron ripoff. It is not too worth it.

2.Should Armaldo get more abilities?

Yeah sure. It has two okay abilities, but both of them are horribly unfitting. It needs something like Hyper Cutter or Touch Claws. Or let's have full list again:

1. Contrary
2. Hyper Cutter
3. Sand Force
4. Sand Rush
5. Sand Stream 
6. Sand Veil
7. Shed Skin
8. Sniper
9. Super Luck
10. Sturdy
11. Swarm
12. Tough Claws

3.Should Armaldo get more moves?

Yep, its movepool is pretty dry. But first, it should get Bug Bite instead of the other Slash like its pre-evolution. After that ORAS goof is fixed, here's a full list of potential moves:

1. Echoed Voice
2. Waterfall
3. Infestation
4. Gyro Ball
5. Nature Power
6. Payback
7. Poison Jab
8. Power-Up Punch
9. Quash
10. Retaliate
11. Safeguard
12. Shadow Claw
13. Steel Wing
14. Dual Chop
15. Fire Punch
16. Hyper Voice
17. Ice Punch
18. Iron Head
19. Thunder Punch
20. Uproar
21. Zen Headbutt
22. Acupressure
23. Crabhammer
24. Cross Chop
25. Focus Energy
26. Hammer Arm
27. Head Smash
28. Leaf Blade
29. Night Slash
30. Psycho Cut
31. Rock Climb
32. Sand Tomb
33. Supersonic
34. Low Sweep

In general more Steel and Fighting moves would be fitting.

4.What additional typing Armaldo can have?

Water, Normal, Steel and Fighting are the most obvious choices. Ground and Dark are also choices.
