All TCGs make cards harder to get even if their the same rarity. Charazards are harder to get in Pokemon, Yugioh has short print secret rares and MTG make things like shock lands harder to get.
@CommandoDeath7322: They have done this before without them going CR. It dosnt mean they wont but it dosnt mean they will.
@UM_AaaBattery no offense but that is just blatantly not true, secret rares have always been a separate rarity in Yu-gi-oh, Charizards did not have a shorter print run than any other holo rare in pokemon, and shock lands have the same drop rate as any other rare from their respective set, the only exception obviously being when Khans fetch lands were put in the land slot of Fate Reforged packs. Long story short, is that there is no evidence of cards of the same rarity being more scarce than other cards of the same rarity.
