The two systems thing is not that much of a problem as I can use a friends 3DS if needed at times. I will also be subbing for the poke bank, which seems like incredible value.
I have already pre-ordered OR, so yeah question remains which of the two options is more ideal(ie. getting Y or getting Pokemon White 2). Also for the mega stones, is the only way to get the ones unavailable to trade for them?
Sorry for the questions and thankyou!
White 2 and Y are both good value, W2 will give you Latias, since you're buying OR which will have Latios, so that sorts out the Eon duo for you. W2 also lets you get the Lake Trio (Azelf, Mesprit, Uxie), Reshiram, Kyurem, Swords of Justice (Cobalion, Virizion, Terrakion), Cresselia, Heatran, Regirock and Regice.
If you have a friend with Black 2 you can get Regigigas if you get a B2 Registeel traded to your game.
And if you get Pokemon Dream Radar, you can get the Weather Trio in Tornadus, Thundurus, and Landorus. If you have the gen 4 games with DR you can get the Johto Guardians and Sinnoh Dragons as well.
Xy has the best breeding system and path, especially since ORAS is all water like RSE likely.
If you get Bank before Sept 30 you can get a Gen 6 Celebi in XY.
Edit: And speaking of Legendaries, I'm the resident Legendary Farmer/Rancher/Hustler, Legendary Hustler sounds best actually. Lol
I can provide you all the Dream Radar Legendaries (Unova Genies, Sinnoh Dragons, Johto Guardians) complete with your own trainer name (not exceeding 7 characters, but this character limit is removed in Gen 6) and gender. All these legendaries have their hidden abilities in dream balls too.
And I can also throw in an Ageto Celebi and Wishmaker Jirachi, which you can choose from below:
