This thread will be tightly moderated to keep discussion focused/on topic/whatever.
Okay so from what you can tell from a Tournament Match & several posts in Feedback what the problem is. A lack of codification on Mega Evolution rules has lead to conflict over what the actual mechanics are, & that is because the Mega Evolution rules tell us nothing on what exactly to do! :o
So I guess we need a few discussion points to get the ball rolling...Mega Pokemon Clause is a new Clause in CAP ASB XY, and the battlers can set the number of Mega Pokemon they want to allow in a battle. (E.G. No Megas, 1 Mega, Unlimited Megas etc.) Mega Pokemon Stones are linked to the Pokemon specifically and, like in-game, are not subject to any item removal or suppression effects such as Trick, Switcheroo, Embargo, or Magic Room. Knock Off does not get the power boost on a Pokemon holding a Mega Stone. In ASB, Mega Evolved Pokemon retain all of their base form's Abilities, and several Mega Pokemon that duplicate base form abilities have associated effects noted on their Mega Stone's Item Description. In Single Ability Battles, Mega Evolutions will have the ability of the Mega Evolution after Mega Evolving, but will retain any effects from the base form's ability (ex. a Moxie Pinsir that got an attack boost before Mega Evolving.)
A Pokemon can Mega Evolve on any action in a round under any condition (Except before the first action of a round), including Sleep, Freeze, or Taunt. Mega Evolution does not itself take up an action, and does not have an inherent Energy Cost (it may activate abilities that do, such as Drought or Sand Stream). Mega Evolution occurs before any other action takes place, regardless of priority (Pokemon will mega Evolve in the speed order of the Pokemon if multiple Pokemon are Mega Evolving). Mega Evolved Pokemon remain Mega Evolved for the duration of the battle once they have activated Mega Evolution. Mega Evolved Pokemon will act with the speed priority they had prior to Mega Evolving on the Mega Evolution action, but will act with their updated Speed in subsequent actions. Their ability will be in effect immediately (ex. Mega Charizard Y summoning Drought), as will the updated accuracy boost if they have a +Spe nature.
Mega Evolution can be used as part of a Chance Substitution if the Pokemon has not yet Mega-Evolved. (ex. Charizard Mega Evolve A2 if X uses Rain Dance A1)
- Mega Evolution on send-out: This goes against in-game precedent, & removes the art of surprise. There is another trivial issue involving doing this, before the opponent switch phases, before you counter-switch that will need to be resolved. In spite of that, should we allow this? If so, when should it happen? Why?
- Mega Evolutions vs. Substitutions: Okay so I schedule a Mega Evolution for A1, & create a non-push back substitution for some move. Then it triggers for A1. What happens to the Mega Evolution? Should my Pokémon mega evolve irrespective of the substitution, or does the Mega Evolution action get overridden & never occur? What should happen & why?
- Mega Evolution Syntax: Mega Evolve\n<action-string> (\n meaning new line for those who have never coded in C or whatever else uses it) is a subject of controversy due to inconsistency in allowance, primarily due to it not being actually tied to a particular action, unlike (Mega Evolve) <Action>. Should it be allowed as far as allowing a mega evolution is concerned? If so, should it be defaulted/tied/whatever to a particular action? Why?
- Mega evolved Pokémon fainting then reviving: So a trainer's Mega Pokémon has died & they have no mega evolutions left. Some crazy mechanic triggers & their Mega Pokémon is revived. Should it come back as their Mega Pokémon? If not, then should they be able to re-mega evolve if they have no mega evolutions left? In-game precedent says no to both, but should it be different in ASB? Why?
General forum rules apply here, so no flaming/trolling etc., as it may result in your post being warned.
Otherwise, time to tackle this issue... @_@
