Magic: the Gathering Standard decks are still diversified based on deck building with the inclusion of several powerful Enchantments in the main deck. The same setting can also be applied to older formats like Modern, and Legacy.

The inclusion of enchantments in the Magic: The Gathering main deck build is important for several reasons, and it largely depends on the strategy and goals of the deck.

Here are some key reasons why enchantments are often included in the main deck:

Diversifying Threats: Enchantments add diversity to the types of threats a deck can present. In a game where opponents may have specific answers or defenses against creatures or spells, enchantments offer an alternative threat that can catch opponents off guard.

Persistent Effects: Enchantments often provide continuous effects that persist on the battlefield. Unlike instants or sorceries that have a one-time impact, enchantments can influence the game as long as they remain on the battlefield. This can create a lasting advantage for the player.

Resource Efficiency: Enchantments can be more resource-efficient than creatures or other permanents. Once on the battlefield, they typically require minimal additional resources to maintain their effect. This can be advantageous, especially in decks that want to maximize their mana efficiency.

Enhancing Creatures: Enchantments can buff creatures, providing them with additional power, toughness, or other abilities. Auras, in particular, are enchantments that attach to creatures, enhancing their capabilities. Cards like “Rancor” or “Ethereal Armor” exemplify this strategy.

Control Elements: Enchantments are often used as control elements in decks. Cards like “Pacifism” or “Oblivion Ring” can neutralize opposing creatures, preventing them from attacking or using their abilities.

Hexproof and Shroud: Some enchantments grant hexproof or shroud to creatures, making them difficult to target with an opponent’s spells. This protection can be crucial in protecting key creatures from removal or disruption.

Win Conditions: Certain enchantments serve as win conditions on their own. For example, decks focused on enchantments might include cards like “Sigil of the Empty Throne” or “Starfield of Nyx” that turn enchantments into a win condition.

Lifegain and Utility: Enchantments can provide valuable utility effects, such as life gain, card draw, or additional mana production. For example, “Courser of Kruphix” is an enchantment creature that provides card advantage and life gain.

Deck Synergy: In some decks, the inclusion of enchantments is part of a broader synergy or theme. For instance, an enchantment-based deck may leverage cards with the constellation or devotion mechanics to maximize the impact of enchantments.

Artifact and Enchantment Interaction: Some decks may benefit from having enchantments that specifically interact with artifacts. Enchantments like “Enchanted Evening” can turn all other permanents into enchantments, enabling synergies with cards that care about enchantments or artifacts.

It’s important to note that the inclusion of enchantments should be considered within the context of the deck’s overall strategy, the format being played, and the expected metagame. While enchantments can provide powerful effects, they are also susceptible to certain types of removal, such as “Disenchant” or “Naturalize,” so players need to balance their deck composition accordingly.
