D Rules 4 this

Sinlocke Rules:

Poke’mon:
*Catch only the first poke’mon you meet in an area.
*Give each Poke’mon a nickname as soon as you catch it.
*If you meet a double first of a poke’mon you have or evolution of one, you can pass it over until you meet one that’s new. You cannot have two of the same poke’mon or one from its line.
*If you knock out the first poke’mon you meet, you aren’t allowed to catch anything else in that area.
*Poke’mon faints, put in the PC storage with a tab called “Fallen”. These stay in there until after you beat the champion and then you give them all a 2nd life.
*You’re allowed to trade but only if it’s a requirement for it to evolve, no exceptions.
*Legendary poke’mon are forbidden. You may catch them but are not allowed to battle.

Items:
*No healing items used at all. No hold items, i.e. Miracle See and Charcoal.
*Only exception are Mega Stones but you may only use them once per battle. If you switch out the mega evolved poke’mon, you can’t use the mega evolution again.
*You may only buy six poke’ball of one type in a poke’mart when you get to a new area.
*No exp. share.
