Severus Snape, Potions Master

Severus Snape, Potions Master's power is equal
to the number of Potion tokens anywhere on
the battlefield.
{u/b}: Put a colourless Potion token onto the
battlefield
{u/b}{t}: Target player discards a card.
"Would you like me to do it now?" asked Snape, his
voice heavy with irony. "Or would you like a few
moments to compose an epitaph?"
