First post here, sorry if this is redundant. I did some searches here on the forum but didn't find the same question. 

If my mage casts a Seeking Dispel onto an opposing creature who has stacked Enchantments, do I get to pick which Enchantment gets dispelled? Does the creature's controller pick? or is it FIFO, LIFO? 

Thanks in advance for taking the time to help out!
