Because of their exclusive distribution, they are often considered even rarer than mainstream chase cards
Most of the WoW quests draw you a card for around the equivalent of 4 mana, bounce lands sort of draw you a land for two but you are forced to pay that cost when you make it
Just flicker Peregrine Drake as many times as you need, tapping five lands every time, and you'll have a profit of at least two mana per loop
For fighting aggro, I prefer Lovestruck Beast to something like Nyleas Disciple
By turning all nonbasic lands into Mountains, Blood Moon has the potential to either stall or completely devastate your opponents mana base depending on the deck theyre playing
Thopter Spy Network requires too much work to be good, and even if you already control an artifact, it's still going to take five turns to get your mana's worth
