[RATE MY TEAM] Netherlandish's Teams

[Netherlandish]

Taking the advice y'all have given me, I began breeding a new Absol for my team, and have come up with thus;

Aderyn (Absol) (F) @ Absolite
Ability: Super Luck
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Sucker Punch
- Knock Off
- Play Rough
- Superpower
With ridding Fire Blast, I can shift the EVs placed into SpA all into Spe to make her even faster, and I'm throwing the final four EVs into Def because eh. Also the Play Rough adds type coverage that I didn't have prior, since I was completely unaware that Absol could learn a fairy-type move.
I've also began working out a Chesnaught build that I previously mentioned.

Machalite (Chesnaught) @ Leftovers
Ability: Bulletproof
EVs: 252 HP / 252 Def / 4 SpD
Impish Nature
- Spiky Shield
- Leech Seed
- Spikes
- Wood Hammer
I'm thinking that he'd be a good support poké while also bringing some stall to the table. Set up leech seed and spikes for some minor chip damage, spiky shield for protection so he can heal up with leftovers and leech seed while also providing chip damage. I could exchange him for my Doublade as having a ghost type on my team is nullified when I have my Absol who covers most of the same areas.
So what do y'all think? Would these make for better additions, or am I completely out of the ballpark? I've been picking up what everyone is putting down and just trying to make it work without doing a complete overhaul on my team.

EDIT: I just had the idea to replace my Sylveon's Moodblast with Calm Mind to buff that SpA stat even moreso. Would you reckon this is a good idea, or what're your thoughts?
