Erode - Secrets of Strixhaven (Rare) [SOS-15]

Erode is a one-mana instant from Secrets of Strixhaven that allows you to destroy a target creature or planeswalker, but at a cost to your opponent. After the destruction, they can search their library for a basic land card and put it onto the battlefield tapped, which can help them recover from losing a key piece. This card is valuable in control strategies where you want to eliminate threats while managing your opponent's resources. However, the downside is that it provides your opponent with ramp, which can be a concern if they have a lot of lands left in their deck.
