Many would say so. Wizards of the Coast, the makers of Magic the Gathering, have worked very hard at balancing the two sides of the coin. On one side, they design cards such that power levels determine the demand (and thus price) for rarer cards on the resale market, and on the other they argue that the cards have no intrinsic value so that buying packs can’t count as gambling since there’s technically no expected profit for the buyers.
