4 rulings from Wizards of the Coast
- 19 March 2021While resolving the triggered ability of Stronghold Rats, each player chooses a card in hand without revealing it, then all of the cards are discarded at the same time.
- 19 March 2021If an attacking creature has multiple evasion abilities, such as shadow and flying, a creature can block it only if that creature satisfies all of the appropriate evasion abilities.
- 19 March 2021Multiple instances of shadow on the same creature are redundant.
- 19 March 2021Once a creature has been blocked, that creature remains blocked and will deal and be dealt combat damage even if it gains or loses shadow or if the blocking creature gains or loses shadow.
