Eventually, you'll have so many boosters for so many cards you aren't using that the accumulation won't matter to you.
And yeah, it seems like later cards might break the game, but generally, they don't. Like, a Galactus/Knull combo feels unbeatable, BUT... if the other player has Shang-Chi or Enchantress? There goes your Knull. Or if they just have a card stronger than 2 they can play PLUS a Knull of their own, same deal.
