Enchantement
Quand l'Épreuve de solidarité arrive sur le champ de bataille, les créatures que vous contrôlez gagnent +2/+1 et acquièrent la vigilance jusqu'à la fin du tour.
Quand un cartouche arrive sur le champ de bataille sous votre contrôle, renvoyez l'Épreuve de solidarité dans la main de son propriétaire.
If an effect allows you to exert a creature as it attacks, you may do so even if it has vigilance. It won’t be tapped.
Trial of Solidarity’s triggered ability affects only creatures you control at the time it resolves. It won’t affect creatures that come under your control later in the turn.
Each Trial has an ability to return to your hand when a Cartouche enters the battlefield under your control. The Trial is returned to its owner’s hand only if it’s on the battlefield as the ability resolves.
