MAGIC: THE GATHERING
You may play any number of additional lands on each of your turns.
Whenever you play a land, if it wasn't the first land you played this turn, Fastbond deals 1 damage to you.
Fastbond has the ability to do outrageous things when combined with Gush, where you're able to float mana and then replay the lands you returned to your hand. All you have to do from there is add in Monastery Mentor or a lethal Tendrils of Agony!
