Kiora, Sovereign of the Deep, numbered 170 in March of the Machine: The Aftermath, stands as a powerful anchor for blue-green strategies in Magic: The Gathering. Released in 2023, this Mythic Rare card introduces a legendary Merfolk Noble that commands respect through both defensive resilience and aggressive card advantage. The card features a mana cost of {3}{G}{U}, positioning it as a pivotal play in mid-range and control decks that seek to dominate the late game. Its design emphasizes the subject's authority over the deep, fitting seamlessly into the broader narrative of the March of the Machine block where aquatic threats reshape the battlefield. Gameplay-wise, Kiora brings Vigilance and Ward {3}, ensuring she can block threats without exposing your life total while deterring small removal spells. The true power lies in her triggered ability: whenever you cast a Kraken, Leviathan, Octopus, or Serpent spell from your hand, you look at the top X cards of your library, where X is that spell's mana value. You may then cast a spell with a lesser mana value from among those cards for free, effectively generating massive card selection and tempo. This mechanic rewards players for building around high-value sea monsters, making Kiora a cornerstone for decks leveraging the Serpent and Kraken archetypes. As a Mythic Rare, this card is highly sought after by players aiming to construct competitive lists and by collectors looking to complete the March of the Machine: The Aftermath set. The product identity remains consistent across all listings, focusing on the card’s role as a key legendary creature in the Magic: The Gathering trading card game ecosystem.
