Arcane Encyclopedia⁣ - Core 2019⁣ (Uncommon)⁣ [227]

Arcane Encyclopedia allows you to pay three mana and tap it to draw a card, providing a reliable source of card advantage. Its low activation cost makes it suitable for control decks that need to maintain card flow while developing their board state. However, it does require a mana investment upfront and may compete with other more impactful spells later in the game.
