Thank you all for the kind suggestions and advice. Looks like these World Championship decks can be my best bet, especially for PTCGO. Since I won't be buying new cards, that also means no new code cards of the new sets so I won't be able to get the new cards and feel like I am behind when I am on PTCGO.
I'm actually a bit confused now. ^^'
1) I've never purchased a
World Championship Deck, but I double-checked; while they come with a PTCGO redemption code, it is for a deck box, sleeves, and coin. Of course, for playing with physical cards, none of that matters but the above post did keep mentioning the PTCGO.
2) If you purchase a real-life
Theme Deck, the ones that release alongside each new expansion, they
do come with a PTCGO redemption code for the actual deck. You may
also just spend 500 Tokens to purchase them from the in-game store, which I have done for
every theme deck currently available there. Either way, you'll have
all cards from the Theme Deck available for building decks in Standard, Expanded, Legacy, or Unlimited (assuming the cards are still legal for the Format in question), plus you'll have the deck for the Theme Format. Sadly, there aren't Theme Format tournaments for the physical TCG, which is a shame; it is a great way for "casuals" to enter the game and get a taste for competitive play.
3) As for keeping up with the new sets on the PTCGO, I'm more or less keeping up without spending any money on it. Too much time? Definitely at first, but not too bad now. The main thing is to learn how to trade and when it is best to grind some Event (in-game tournament) wins for Trading Fodder. Now, if you have almost
no time then yeah, those options don't work too well.
So... with all of that said, still confused with your post talking about buy World Championship Theme Decks for the PTCGO. @_@ Did I just have a reading comprehension fail or what?
