Legendary Creature â Vedalken Artificer
Artifacts you control have hexproof.
At the beginning of your upkeep, if you control the artifact with the highest converted mana cost or tied for the highest converted mana cost, draw a card.
Matt Stewart INTERVIEW
The artifact you control has to have the highest converted mana cost only among artifacts on the battlefield, not among all permanents on the battlefield.
If you no longer control an artifact with the highest converted mana cost as Padeemâ€™s triggered ability resolves, you donâ€™t draw a card.
If you donâ€™t control an artifact with the highest converted mana cost as your upkeep begins, Padeemâ€™s second ability wonâ€™t trigger. You canâ€™t cast an instant to destroy an opponentâ€™s artifact during your turn before your upkeep begins.
If an artifact has in its mana cost, X is considered to be 0.
