I was playing Gen 8 random monotype, and led with Mew. The opponent led with Salazzle. Mew used Toxic Spikes, and the sprite showed up. The Salazzle used Toxic so I switched. My Metagross used Stealth Rock as a Charizard switched in. Nothing happened to it, Heavy Duty Boots I presume. Salazzle switched back in and the toxic spikes disappeared for some reason? Anyway Mew came back in and used Toxic Spikes twice. Charizard came out and dynamaxed, was cheap, etc etc. Salazzle switched back in, and the toxic spikes nor stealth rocks did anything, even tho their sprites were clearly there. Were they both just wearing heavy duty boots?
