Okay, so I have {Glint Hawk Idol} and a {Mox Opal} in play, I play another {Mox Opal}, yes they destroy each other, but does it trigger the Idol into becoming a 2/2 flier for the turn?
Yep. It did touchdown before getting obliterated.
Hah okay, I was playtesting my {Tempered Steel} and was just curious if that would work.
