^ Same thing with BW base set. Samurott, Emboar and Serperior were together. Then they got seperated.
No? The BW starters have all appeared together in sets (with the exception of Shiny reprints and Serperior from Shiny Collection).
But what DNA said is correct. Starters usually appear together if they're the starters of that respective gen. The others might appear together but may also be spreaded around or paired with starters from other gens.
To be more specific. It all started with DP. In the DP block, not counting pokémon variants (like Pokémon SP or shinies in BW), we had the following:
DP: Sinnoh starters together
MT: Johto starters together
SW: Kanto starters together
GE: Hoenn starters together
MD: Another wave of Sinnoh starters
LA: none
Then, you can count Stormfront as already part of the second block of sets or put it apart from the Platinum sets, because with the Arceus set, it all ends up the same way. But it was in Stormfront where they started to spread and combine the Kanto and Hoenn starters while leaving the Sinnoh starters together and saving the Johto ones for the HGSS-block.
SF: fully evolved Sinnoh starters together (in their secondary type); Sceptile (as a regular card) and Charizard (as a retro card) combined.
PL: 3rd wave of Sinnoh starters; Blastoise and Blaziken combined.
RR: none (again, not counting things like Infernape 4 or Turtwig GL)
SV: Venusaur and Swampert combined.
AR: Charizard and Sceptile combined again. Though, Sceptile had 2 cards and none of them were holo. [The Charizard and Sceptile combination was always the weird one]
HGSS-block:
HGSS: Johto starters together
UL: There's Blastoise and Torterra but they came from special decks and then, no other starters were released during the HGSS-block except...
CoL: reprints of HGSS johto starters.
BW:
BW: Unova starters together (2 of each, one from the Beginning sets and one from the main set)
-note: BW Promo reprints also released together...
DEX: Empoleon, Venusaur and Blaziken
BC: Charizard and Blastoise; 2nd wave of Unova starters
PLS: Infernape and Torterra (as Plasma pokémon)
PLF: Sceptile
PLB: Blastoise reprint from the Kyurem-EX+Blastoise deck (doesn't count as a new release as it is simply a reprint from a special deck).
EBB: BW main set's Unova starters reprinted together. Charizard is also reprinted and there's a new Empoleon.
Still in the BW era, there's the Empoleon promo, a japanese-only (for now) Serperior promo and like I mentioned above, the Serperior from Shiny Collection (which is a special set).
Also, there's the shiny reprints:
Emboar appeared in NXD, Serperior in DRX and Samurott never had one, hence why those shouldn't count for the purpose of this post. Finally, there's shiny Charizard and Blastoise in PLS (Venusaur never had a shiny) and shiny Empoleon in PLF.
Special notes to Swampert never having a BW release nor the Johto starters (but those had been released in the previous HGSS-block).
PS: This is way I prefer the DP block over BW. It was much better organized...
