Since in Super you connect with Pokemon way stronger than yourself, I barely use me and my partner. I'm level 23 and my partner is 20. I went to a sand continent dungeon to do 3 jobs. 8 of my 10 best Pokemon were unavailable, so I ended up going with a level 56 Alakazam, a level 55 Bisharp and a level 42 Rhyperior. I needed to get through all 11 floors.
Floor 4.
I had used a Scanner Orb earlier that floor, and I could see a room absolutely loaded with items. It had 4 items and 3 emeras on the ground. So, I took control of Bisharp and waltzed in there, and then right as I moved into the room, I remembered something horrible.
"If a room has too many items and looks too good to be true, it's a monster house." I find myself one step out of a corridor, in this cramped room with 4 Klangs, 5 Magnetons, 2 Slurpuff and 3 Porygon2 staring at me. At this point I knew I was buggered, so I decided to go out with a bang. Alakazam behind me using Psybeam and Rhyperior behind him using Rock Wrecker, we were doing damage. We were also taking damage. I noticed my last Oran Berry disappear from my bag. Then a Porygon2 used Agility and suddenly everything else was moving sanic fast. At this point I was at +4 from Defiant boosts because the Slurpuffs spammed Sweet Scent from across the room. Then this Porygon2 used Zap Cannon and it hit.
I stand here, paralysed. Waiting to be beaten. Then the Klang in front of me Gear Grinds me, and I faint. But now I'm even more screwed because it evolved into a Klinklang. Then a Magnetite sneaks a Thunderbolt around the corner and gets my Alakazam. So, I take control of my Rhyperior and run like mad, hoping I can find the stairs. But running through this long corridor, a Porygon2 blocks me. I'm not scared of it, I know Hammer Arm. Then Hammer Arm misses.
AND THE KLINKLANG FOLLOWED ME! IT WAS RIGHT BEHIND ME! Then I tried to hit the Klinklang with Drill Run as it came closer. I KO'ed it. But one space behind it was a Klang, and at this point I have 12 HP. The Porygon2 Psybeams me, it somehow misses and then the Klang grinds my Rhyperior into dust. That probably wasn't the ideal way to come out of a Monster House.
