New Abilities and Signature Move buffs for mega evolutions of Kalos(Gen VI) Starters.
The idea was to make these three more viable in the champions meta without making them too overpowered and changing their roles. I also gave their original signatures moves some buffs so as mega pokemons they suit them more.
Mega Chesnaught: This is a bulky wall, so the idea is to make it harder to get rid of, but with such horrible typing not much can be done but reducing the effects of super effective damage makes it so it can stay longer on the field and can be annoying for longer period of time. The spikey Shield buff also gives it a passive healing like a leftover that punishes attacking into it while protected.
Mega Greninja: It now gets the freedom of switching abilities and as a pokemon that used speed to catch pokemon attacking it off Guard giving it an ability that capitalises speed seems fair, this makes moves like tailwind and sticky webs even more important. The Water Shuriken change can allow it to damage and pick off weakened pokemons easily and also makes water Shuriken to run as the only water stab option as well.
Mega Delphox: It is already an amazing Pokemon in current meta so I didn't wanna buff it too much so it seems like the most weaker of those three in buffs but the idea is it becomes more viable for singles by being immune to entry hazards such as stealth rocks as well, gives it much easier time switching in and attacking. And the change to Mystical fire gives it the ability to not only weaken special damage but potentially even physical damage.
Overall the idea is these changes can elevate these pokemon in current meta to maybe not immediate threats but not such a bad spot as they are currently.
