Baton de tonnerre

Je l'ai en jeu. Deux 1/1 m'attaquent. Je perds 1 ou 0 ?

Tu perds 0 si le baton est dégagé.
Ca prévient 1 point de dégat sur chaque créature attaquante.

Voilà voilà

Sûr et certain?

Ouiiiiiiiiiiiiiiiii, sur et certain.

Saturday School questions matching "thunderstaff"
From Saturday School #66 by Rune Horvik, Saturday, February 21, 2004:

Q: I have an untapped Thunderstaff in play. If my opponent attacks me with three creatures, can I prevent one damage from each creature (similar to what Urza's Armor did) or can I only prevent one damage from one creature?

A: Thunderstaff prevents one damage from each creature that deals damage to you, and since each creature in combat deals damage separately, one damage from each unblocked attacker will be prevented.
