Two aura enchantment questions
Just finished a game of draft Wilds of Eldraine in MTGA, a set I'm not too familiar with, and had two unexpected interactions that I wanted to ask about, both having to do with Aura Enchantments.
An opponent cast [[Bitter Chill]] on my [[Faunsbane Troll]]. Why couldn't I use the troll's ability to sac the aura for a benefit?
I used [[Eriette's Tempting Apple]] to gain control of an opponent's creature that had [[Curiosity]] attached to it. When it dealt damage to the opponent, why didn't I draw a card?
Thanks!
