Phantasmal Forces⁣ - Fifth Edition⁣ (Uncommon)

Phantasmal Forces is a 4/1 flying creature for three generic and one blue mana. When you play it, you can attack your opponent in the air, but each turn during your upkeep, you need to pay one blue mana to keep it on the battlefield; otherwise, you have to sacrifice it. This card can be useful for applying early pressure to your opponent or for providing a flying blocker, but the need to pay mana each turn can be a significant downside, especially in a tight mana situation.
