Not Enough Mana

From BoardGameGeek:

Not Enough Mana is a "potion" drinking card game for 3-6 fearless wizards (legal potion drinking age may vary depending on your kingdom's laws). You'll be destroying each other using epic spells, curses and artifacts while replenishing your mana by drinking magical potions*. Your goal is to eliminate all other wizards from the game, either through depleting all their health points or by K.O. (also known as Too Much Mana). In their turn, players cast spells and curses, equip artifacts and face epic events by drawing and playing cards. Spells require mana points, which the player can replenish at any point in the game by drinking mana potions. If a player loses all health points or is incapable of making a move on their turn, they are removed from the game. The last player wins.
