Umbra Stalker

Creature - Elemental X/X, 4BBB (7)
Chroma - Umbra Stalker's power and toughness are each equal to the number of black mana symbols in the mana costs of cards in your graveyard.¹
Don't venture into the darkness, lest it decide not to let you leave.

Gatherer Card Rulings [Nov 2009]

• 8/1/2008: This is a characteristic-defining ability, which means it functions in all zones. You include the symbols in the Stalker's own mana cost if you need to determine its power and/or toughness while it's in the graveyard.
• 8/1/2008: Chroma abilities check only mana costs, which are found in a card's upper right corner. They don't count mana symbols that appear in a card's text box.
• 8/1/2008: Chroma abilities count hybrid mana symbols of the appropriate color. For example, a card with mana cost {3}{U/R}{U/R} has two red mana symbols in its mana cost.
