Tried to start a five-star raid against a flying-type Annihilape. All three partners sent out Iron Hands and immediately led with Belly Drum. You'll never guess what happened next! It starts with "C" and ends with "lose Combat sweep".
You also have to be able to defeat a seven star Charizard. No mean feat with how laggy the game gets while playing online. I'm hearing that a properly built Azumarill can handle it , but I have to finish leveling one first.
I gotta say, I love the headline. No name, just calling an idiot an idiot.
In certain, extreme, and very specific cases, it may be justifiable. Rhinox's example is one; the gunman clearly had no intention of surrendering or any goal beyond mass murder. But in general? It's a terrifying idea.
I only found a shiny Venomoth because my mons wouldn't fight it on auto battle mode. The Sandygast was a bit more obviously different, thankfully. Haven't noticed any others, which, of course, doesn't mean they weren't there.
