My PM:
" https://www.youtube.com/watch?v=Jkk2zUPO2Jo The trigger, healthy pokemon in, switch into low hp pokemon that dies to the hazard (spikes or rocks), spam attack, 1-1 on your keyboard or press ATTACK and choose a move as quickly as possible
https://www.youtube.com/watch?v=OF3Ni3T2bB4 if your pokemon died and you swap into a pokemon with low hp that dies to the hazards = no trigger
https://www.youtube.com/watch?v=8AQoTw6ksUk pretty much #1 but I didn't press attack this time = no trigger
https://www.youtube.com/watch?v=KT-lGUhVjp4 whirlwind/roar switches to a pokemon that would die to the hazards = no trigger
I tried to explain it as easy as possible :P
Greetings :)"
