Trick Room

I Usually Like Speed, So Trick Room Team Just Denys It And It's So Annoying. Luckily, It's Pretty Uncommon, But You Just Suffer Through It Whenever You See It. It's Especially Bad With Stackatacka, Which Can Sweep For As Long As The Trick Room Allows It To.

Wish

Don't See It Much, But It's Annoying To Be Wish Stalled By Some Person Who Uses Like Glaceon Or Something. Can Also Heal Other Pokemon From Ur Team If You Like, Which Gives It A Bit Of Variety.

Every Healing Move

Heals You By 50%, Which Is Absurd. Chances Are, Your Probably Going To Deal Less Then 50% Each Move. So These Moves Can Just Be Spammed. (Commonly Known As 'Roost Spamming' Or Something)

Taunt And Torment

Makes Me A Hypocrite Because I Use Taunt On My Suicide Lead Mew. Both Of Them Are Annoying To Deal With Because Of How Much It Denies. Taunt Is Worse, Though Torment Is Pretty Bad To.

Moves Like Roar That Force The Oppenent's Pokemon Out

This Is Annoying To Deal With Because These Moves Can Deny A Lot And Have Quite A Bit Of Variety. Oppenent Finishes A Setup? Use Roar. Have Entry Hazards On Their Field? Use Roar To Chip Away Their Health.

Defog And Rapid Spin

Removes Entry Hazards. The Only Reason Why I Have Mew On My Team. For It To Setup Entry Hazards And Explode. This Is Just Me.
Protect

This Move Has A Truck Load Of Variety In Not Only Singles, But Doubles, Free-For-All, Triple Battles, Multi-Battle And Might Be More. There's Clones Of This Move That Are Even More Annoying, Like King's Shield And Baneful Bunker.

Entry Hazards

Once Again, I Am A Hypocrite. However, I Only Use Spikes And Stealth Rocks. Why Do I Mention This? Toxic Spikes And Sticky Web. Look It Up What Those Moves Do, My Hand Hurts A Litltle From Typing. Ok Fine. Toxic Spikes Can Go Up To 2 Layers, One Is Poison And Two In Toxic. And Then Sticky Web Gives U Webs That Lower Ur Mons Speed Stat By One Stage. Thankfully, It Only Affects Grounded Oppenents. Thank Goodness For My Heavy-Duty Booted Zeraora, As All My Mons Are Grounded And I Only Have 1 Steel Type.

Honorable Mention: Subsitute

Not That Bad, But Still Quite Annoying. Arguably Better Then Protect, But It's Less Annoying And For Me, I Have Dragapult With Infiltrator.

Item: Choice Scarf

I'm Leaving This As An Added Bonus. The Main Reason Why I Hate This Item Is Because It's So Unexpected. You Think You'll Outspeed The Landorus Your Fighting And You Think It's All Gonna Be Alright Then Sike, It's Scarfed.

That's It. Probably Missing A Move Or 2. Might Do A Sequel Post Discussing A Few More Annoying Moves. And Maybe A Few Items And Abilities.

note: i no longer use a suicide lead mew and dragapult. all of these opinions are still true to this day with a brand new team. sticky web is now less annoying for me because i have defiant bisharp (still really annoying).
