法术
选择目标由你操控的生物和目标不由你操控的生物。如果该由你操控的生物是骑士,则它得+2/+1直到回合结束。然后这些生物互斗。(它们各向对方造成等同于本身力量的伤害。)
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.
