>>30602917I got banned from my first tourney attempted because I had five masterballs, which was over the legal three, so they banned me because I had been "cheating". I had no gameshark or action replay at that point, and in fact I had been repeatedly been playing Sapphire over and over to transfer masterballs with my starters purposefully to catch the legendaries in Pearl and Diamond. Ironically one of my first GTS mons was also Lopunny caught on Route 2 at level 100 that was also holding a Masterball, so there was one there too.
I was fairly butthurt over being banned, and I was traded a Shaymin that someone at that same event had hacked, cloned, and given me. About a week later bought myself an Action Replay out of spite.
I may not have started my tourney journey that day (or ever), but within a month my PC was drowning in shinies, and I caught myself all the legendaries available, mostly on illegal routes. It was a glorious time.
I enjoy a blend of legit and injecting nowadays depending on my mood, but I try to keep one clean copy of the current gen games in case I ever try a local event again. No extra items, no injected-from-scratch Pokemon. Just good "clean" fun.
