My only change I have done is that I will include Litleo in my team, really love Pyroar... so 3 confirmed from me and 3 undecided.
So far I only have 2 Pokemon 100% & 2 like 50% confirmed to be in my team - at least for my first run of the game:
100% Confirmed in my team:
• Chespin, as my starter and main grass Pokemon
• Helioptile, as my electric Pokemon
I may use - 50% chance
• Litleo, that is if no other felines are introduced
• Pancham if no other fighting type introduced I like AND Mienfoo is not available before Elite 4.
Not yet decided, or I may need to wait:
• water type, always need one in my teams
• weasel-based Pokemon of Kalos, if none are introduced then I'll choose Sylveon AND Patrat is not available before Elite 4
I have one more possibility that might leave me an open slot, if two above are mixed (for example another fighting weasel or another water weasel [a.k.a. sea otters], or a water-type cat or a fighting type cat) then the open 6th Pokemon I will choose Sylveon.
So now it would be more like:
100% Confirmed in my team:
• Chespin --> Quilladin, as my starter and main grass Pokemon
• Helioptile, as my electric Pokemon
• Litleo --> Pyroar, as my main fire Pokemon and Feline Pokemon of the region.
Not yet decided, or I may need to wait: - 50%
• water type, always need one in my teams, if none of them I like, I will go with Squirtle, just hoping that Buizel will be catchable in X or Y before Elite 4.
• weasel-based Pokemon of Kalos, if none are introduced then I'll choose Sylveon
AND Patrat is not available before Elite 4
• Pancham if no other fighting type introduced I like
AND Mienfoo is not available before Elite 4.
