Frequently Asked Questions
Q: Does there have to be at least one of each (artifact, creature, enchantment, and land) for me to play Decimate Buy?
A: Yes. You need a legal artifact, creature, enchantment, and land target to be able to cast Decimate Buy, but they need not be different permanents. Because the word "target" is used in multiple instances, the same permanent can be chosen for more than one target as long as it fits the criteria. (For example, Dryad Arbor Buy could be chosen for both the creature and land targets.) If there were no artifacts on the battlefield, you would not be able to cast Decimate Buy, and the same goes for creatures, enchantments, and lands.
