3 rulings from Wizards of the Coast
- 18 April 2017You can’t normally activate abilities of cards in graveyards. Those that you can activate are those that instruct you to move the card out of a graveyard, or those that specifically say that you can activate them if the card is in your graveyard.
- 18 April 2017Activated abilities contain a colon. They’re generally written “[Cost]: [Effect].” Some keyword abilities (such as embalm) are activated abilities and will have colons in their reminder text.
- 18 April 2017Any untapped Zombie you control can be tapped to pay the second ability’s activation cost, even one that just came under your control.
