Shefet Dunes - Hour of Devastation (Uncommon) [HOU-183]

Shefet Dunes is a Desert land that produces colourless mana and can provide white mana at the cost of 1 life. Its activated ability boosts your creatures' power and toughness for a turn when you sacrifice a Desert, making it effective in decks that leverage Desert synergies or flood the board with creatures. However, the ability can only be activated as a sorcery, which limits its use in instant-speed plays.
