Well yes, but at the same time so is your opponent. You both can rely on having the exact cards you want when you want them, which is something deck-games 'suffer' from. You can come up with an awesome idea for a deck, only to find to happen to draw 5 energies in a row and no monsters, and get wipped. The whole-deck solution would elliminate the chance aspect, and come down exactly to what cards you have and when you play them.
If there was a limit to the number of cards in the deck, I think that'd work. It'd be a different experience to real card duels, but I think a game it'd work. Just like if you play any multiplayer game, both teams get to slect from the array of weapons etc. It's not like at the beginning of a Halo multiplayer match, you get dealt one random weapon and another random weapon every five minutes! You don't find you're getting cut down by snipers with no means to retaliate because all you've drawn so far are pistols and grenades! It starts with a level playing field.
The only trouble I can obviously see is someone could just have every card imaginable, and pick all the counter-elementals and traps and whatnot they want. Part of the challenge is working with a limited set of options. In some games that's a finite deck size. In others is limited by what you've drawn, and throwing every card into the deck just dilutes your chances of getting that particular card.
I'm not quite sure I know what you mean. In regular TCG your access to good cards is only limited by money. If you have enough money you can buy every card out there, no skill involved. Choosing among those cards to make a deck requires skill. I don't know the deck size in this particular game, but in Magic TG it was 60+. There is a huge drawback to making a deck with more than 60 cards though, since you can only have any one card at most 4 times in a deck, if your deck is bigger you have less chances of drawing it. This meant that in practice no one went for decks over 60. I suspect in this game the deck size is gonna be 30, since that is what it comes with, and there should be a restriction on how many identical cards you can have, just like any other TGC.
If your "awesome" deck consistently draws 5 energies in a row then it's not so awesome to begin with. You can calculate the exact probability of such an event happening when you're building the deck and needless to say it should be low enough that it happens very sparringly. That's the challenge of building a proper deck, finding the right balance. The fun in playing is that even with the right balance sometimes you just draw crap. Sometimes your deck works like a charm and sometimes it doesn't, you have to adapt.
So I disagree when you say the challenge is working with a limited set of options, sure it's fun to create a competitive deck with lesser cards, but even if you have access to all of them, it's still challenging and as long as the game is properly balanced it shouldn't matter that much if someone has access to all the cards.
