Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I've seen some teams using Eject Button and I don't really understand why it's good - I haven't been able to use it effectively personally, likely due to my inexperience.
It's often used on slower pokemon too, so it means they can be forced to pass their turn. I was watching a video where the...
+1 252+ Atk Tera Normal Dragonite Extreme Speed vs. 4 HP / 0 Def Chien-Pao: 265-313 (87.7 - 103.6%) -- guaranteed OHKO after 1 layer of Spikes
If they get one DD, this isn't a check anymore
Since usually Pokemon will stay in for one turn, I would think 1 layer is actually better than 2. Toxic only does more damage than regular poison if you take damage for 3+ consecutive turns.
Haha, this thread is doing the same Pokemon in the same order as https://www.smogon.com/forums/threads/sv-ou-lure-that-threat-week-3-annihilape-submissions.3712577/
