Baleful Mastery, Tokens, and a Non-Zero X [Investigating]
Event: Standard Training Grounds
Scenario: I cast Baleful Mastery (fully enhanced) on a token, and my opponent took a non-zero amount of damage.
The card says X should be the base mana cost. I would have expected X to equal zero for a token creature.
It's worth pointing out that X was variable against tokens I exiled during this match. The first time I saw this occur, X was equal to one, but the video above shows X equal to two when that token was exiled.
