Even content creators with far more resources than the average person complains about how ludicrously expensive Arena is. PTCGO is dirty cheap in comparison, it's not even close. The grind in Arena is really that, grind, unbelievable, gritty, torturous grind. And it is like that by design, as to force you into just giving up on the feelbad and putting money into the game. Most decks require a ridiculous amount of rares and mythics, and that's just talking standard. Wanna play Historic? That is on a whole new level of ridiculousness. On PTCGO, I spent some money to buy some packs here and there and I have dozens of decks in each format. Plus, the game gives you tickets for literally free, which you can use to (easily) win tournaments and get tradeable packs. It's really a piece of cake. Plus the trade system is the most pure and genuine supply and demand thing ever. With patience and a little bit of understanding you can even make some packs or acquire cards by smart trading. Other than that, only the over-hyped poster-boy of a given set set goes for those ridiculous amounts, but there's pretty much always better options (financially-wise) to go about playing the game, especially standard. For instance, why pay 30 packs for each SR, just because it's the new hot thing, when you can buy other equally competitive stuff for 1/3 of the price (like Ice Rider for instance)? Plus, if you're looking more for variety and fun than competitiveness, you can just forget super expensive cards altogether and build like multiple entire decks with the price of a single SR. Anyway, having played both clients I cannot stress enough how infinitely better than Arena PTCGO's economy is.
