Drowned Rusalka⁣ - Guildpact⁣ (Uncommon)⁣ [24]

Drowned Rusalka is a 1/1 Spirit creature that costs just one blue mana to cast. You can pay one blue mana and sacrifice another creature to discard a card from your hand and then immediately draw a new card. This ability is useful for cycling through your deck to find specific cards you need, particularly in decks that have expendable creatures or ways to generate tokens. However, since Drowned Rusalka is quite fragile with just one toughness, you need to be cautious about when to play it, as it can be easily removed before you get a chance to use its ability.
