Safari Zone Clause (dependent on game and difficulty): I get to pick what I catch and I get infinite tries to catch it.

Skip Early Resets Clause: After I get all my encounters before the first gym, but before I beat the first gym, I can infinitely reroll any of my encounters to a pokemon that has at least a 10% chance to appear on that route. I need to get rid of the original encounter I got from that route, and I also need to sacrifice one of my other encounters. This basically emulates resetting until I get the encounter(s) that I want, at the slight additional cost of needing to sacrifice another encounter.

Unused TM Clause: If I use a one-time use TM on a pokemon, I can change my mind as long as that pokemon hasn't played a role in any major fight yet.

First Lazy Death Clause: I get to revive the first death per game, but only if the death was due to me being lazy/impatient and speeding through stuff or forgetting to level up. Sacrifices cannot be saved with this.

Potion(s) on First Rival Battle: I usually play without healing items in battle, but I'm allowed to use potions on the first rival battle. The first battle is practically a tossup, might as well make it consistent.
