How do you explain that these decks are replacing the french Plasma Blast deck release? Based on this fact, assuming they'll have any BW cards is too far of an assumption
Then what about Mind Wipe and Solar Stirke? What are they supposed to release come February, or whenever their Legendary Treasures is supposed to be released? It is a fact that no matter how you see it, Legendary Treasures doesn't have theme decks associated with it, and as such, I think these decks should contain both XY Kalos Starter set and Legendary treasures cards mixed in them, barring trainers, which can contain cards from almost any set in the series.
It is also most likely that the XY beginning set will be similar to the BW beginning set. This means that there are only 2 or maybe 3 lines that could evolve. Basing on what the card numbering is on Bulbapedia, it seems that the water deck might have metal pokemon in them. Metal comes after Darkness but before Dragon. All types that have their own energy always come before those that don't, so Fairy would most likely be listed after Metal, but before dragon.
The question is, how does TPCi handle something that is a 30 card deck, and turn it into a 60 card deck, and not make the deck boring, or get destroyed by theme decks? Considering the nature of the Beginning sets, and them being 30 card decks as opposed to 60 card decks, there would be probably only one rare equivalent pokemon per deck. So how does TPCi include 5 rare equivalent cards when there is only one to choose from? Here is what I mean by rare equivalent. Take the BW beginning set cards, and take the corresponding cards in the Black and White expansion released internationally. Only Serperior, Emboar, and Samurott turned out to be rares. The rare equivalent of a kalos starter set card would be the rarity it would have been if it were to be released as part of the February XY expansion.
Another thing is evolving pokemon. In a 30 card deck, there is probably enough room for 2 different pokemon lines that could evolve, and that is the case with the BW beginning set, and I assume that would be the case with the xy beginning set. Simply doubling the XY beginning set will still make the 60 deck contain 2 pokemon lines that could evolve, and a ton of basic pokemon that can't evolve or don't evolve because the card isn't included. So how does TPCi counteract the fact that the 39 cards in the XY beginning set don't have a lot of stage 1 or stage 2's due to the nature of being a set for beginners?
I am going to do some speculation.
First thing I am going to speculate is that the Kalos starter set is NOT XY beginning set x2. If it is, then I don't know what TPCi is thinking.
I also speculate that Grass, Fire, and Water will have the 5 pokemon with different names, Darkness, Metal, and Fairy will each have 3 pokemon with different names, 9 colorless pokemon with different names, and 6 trainer cards with different names. This totals 39 cards.
Ok, the first 30 cards probably would be the 30 card XY beginning set deck one for one. I am also going to make assumptions that the make up will be similar to the BW beginning set in terms of deck templating. I am also going to speculate on the chespin deck for example.
Here is what I think Chespin's XY beginning set deck will look like.
2-2-1 chespin line, total 5 cards
1 grass pokemon, total 6 cards
1 grass pokemon, total 7 cards
2-1 granbull line, total 9 cards
1 fairy pokemon, total 10 cards
1 colorless pokemon, total 11 cards
1 colorless pokemon dependent on gender version, total 12 cards
6 trainers but 5 different trainer cards, total 18 cards
12 energy, total 30 cards
Theme decks typicall have 18 energy, so let's add 6 to this. Total is 36 cards.
The stage 2 holo usually is a 4-3-2 line in theme decks. This adds 4 more cards. The total is now 40 cards.
Let us double the granbull line. That is what I think theme decks would have done in the case of a stage 1 that isn't rare, or at least I don't think Granbull would have been a rare if it were to be released in a booster set. This adds another 3 cards. The total is now 43
Let us add 2 more trainers to total 8 trainer cards by doubling 2 more trainer cards. The total is 45 cards.
There is no distinction betweein boys and girls version in the kalos starter set, so both versions are available, this adds one more card. The total is 46 cards.
Let us double the rest of the single basic pokemon lines. This adds 6 cards. The total is 52 cards.
So what would be the remaining 8 cards, while trying to fit this into the theme deck template, and 30 of the cards must be a one for one copy of what the XY beginning set might be?
Let us double the rest of the trainers instead. This adds 2 more cards. We have 54 cards.
Problem still is, not enough rare equivalents and not enough stage 1's.
Here's hoping that the XY beginning set contains at least one more pokemon that could evolve. Looking at the list of colorless pokemon within the 39 card set so far, it looks like none would evolve, and it wouldn't make sense to have one of them evolve. If there were to be a third pokemon line that could evolve within each 30 card deck, it would be Weedle Kakuna, Slugma Magcargo, and the water deck gets an evolving colorless pokemon that probably sits in card slot 30 and 31, but I doubt it. I have a feeling that it would only be 2 evolving pokemon lines, and that doesn't cut it for a theme deck.
