Miracles plays the best defensive cards, but has a proactive game plan. Make no mistake, Counterbalance is an aggressive card because the longer and longer it sits in play, the more and more it constricts the opponent’s options until they can’t win anymore. It may take another 10 turns for Miracles to actually close out the game, but they won a long time ago. Or maybe they drew—I don’t know, the clock is a real thing.
Recent Miracles lists have been playing Predict for card advantage. Predict plays like a mini-Dig-Through-Time in that it can clear bad cards off the top of the deck and give you 2 fresh ones. Clearly it is way worse than Dig, but it still plays a similar role, and having access to a card like this can give Miracles a fighting chance against some of the decks that normally prey on it by 2-for-1ing it a bunch, like Shardless Sultai.
