Forum:Simultaneous Effects Question

My brother and I can't figure out this problem. The two cards are Azure-Eyes Silver Dragon and Fire King High Avatar Garunix. Both of their effects happen during the standby phase. Our question is how do they resolve? Do I get my normal monster from the grave then Garunix destroys everything? Or does Garunix destroy everything then my normal monster is special summoned? --WookieeSwag (talk • contribs) 04:22, December 3, 2013 (UTC)
