If you're wondering about Big Ol' Whelp, it's just because you kind of want to keep all Dragons to get off those holding a dragon cards.
Dragon Priest in Standard? I went the more midrange rather than control route, not sure if this is the most optimal dragon build, but I did go 9 wins out of 13 games, so the deck definitely does something right. Give it a try and optimize it for sure. Also, you could try adding Murozond. I didn’t just because I didn’t have him, but he isn’t a bad option for the deck. Any late game dragon bomb, like Ysera or Alex might work. I also experimented with Amer and Psychopomp, but they’re kind of clunky.
