Oracle's Vault⁣ - Amonkhet⁣ (Rare)⁣ [234]

Oracle's Vault is a four-mana artifact from Amonkhet that allows you to exile the top card of your library for a chance to play it until the end of your turn. By adding brick counters, you can eventually cast cards without paying their mana cost, providing a steady source of card advantage in games. This card fits well in control or combo strategies that aim to maximise resource utilisation, though it requires careful timing and setup to reach its full potential.
