To start off, I went into Pokemon League in my Emerald "Save the Pokemon" challenge, stocked up on healing items, then fought through the first few Elite Four members. Up until Glacia, my Pokemon were doing good, but Drake killed every single one with his Salamence, except for my starter, Swampert. D: Thankfully, Swampert had an awesome Ice Beam, and was able to defeat Salamence. However! I completely forgot healing up right after defeating Drake, because I got used to healing in the room of the next Elite Four member then. Thus, as I entered Wallace's room, I saw my character tread towards Wallace without halting, until I realized, that...I can no longer heal...Wallace just talked to me without giving me any time to do so.
I immediately thought, "This can't be happening." Even though it felt hopeless, I still continued on for I worked so hard to get there. So yeah, my Swampert was sent out against Wallace's Wailord. Thank goodness I had a Max Revive, so at least I can have a fully healed Pokemon from my team try to defeat Wallace. But who can possibly take on Wallace on its own? At first, I looked at Magneton. But then I remembered how useful Gardevoir's Calm Mind was, so I went with it instead. So yeah, I used Max Revive on Gardevoir, and sent it out after Wailord finished my Swampert. )': After almost killing myself with a 60% accurate Hypnosis that I used in the first turn, which amazingly worked, I then set up about three Calm Minds before Wailord wake up. It was going to use Water Spout, and I thought I was a goner. But surprisingly, after using Calm Mind at that turn (yay for its speed) Gardevoir was able to take the attack, so by using Psychic in the next turn, Wailord was beaten. o.O
Right after that, every single Pokemon of Wallace fell to either Shock Wave or Psychic. I did Calm Mind two more times within those last battles, and healed using a Hyper Potion at least once, but after beating Milotic, I just sat there, jaw dropped, not believing how I actually was able to beat the Champion with one Pokemon. So yeah, I guess that means I've got a new Pokemon to add to my favourites. :3
