巫術
選擇目標由你操控的生物和目標不由你操控的生物。如果該由你操控的生物是騎士,則它得+2/+1直到回合結束。然後這些生物互鬥。(它們各向對方造成等同於本身力量的傷害。)
If the creature you control is an illegal target as Joust tries to resolve, no creature gets +2/+1. If that creature is a legal target but the creature you don't control isn't, it still gets +2/+1 until end of turn if it's a Knight.
You can't cast Joust unless you choose both a creature you control and a creature you don't control as targets.
The target creature you control gets +2/+1 only if it's a Knight as Joust resolves. It'll still fight if it doesn't get +2/+1.
If either target is an illegal target as Joust tries to resolve, neither creature will deal or be dealt damage.
