How Potions Work

Potions are something you play for a mana cost. They enter the battlefield, but aren't used immediately. When they enter the battlefield, they do nothing. At any point, (Like an instant) You may sacrifice one. When you sacrifice it, the ability of the card is activated. If these were to be in booster packs, they would be extremely common and you may have up to 10 potions in a deck. You can have 10 of one potion, or 10 different potions.
