In terms of burn, I think
Blue Elemental Blast just worked up on the importance scale. Plus it also catches other decks besides burn as well.
On Goblins, alright. I see what you are saying. Unless there is a meta shift that makes Skullcrack necessary in Goblins, they really don't need the effect as bad as burn. It may see tests, but until then, I say we just move on that front since this isn't a Goblin thread after all. Maybe I'll go peek in on them and see if they've even said anything about Skullcrack... :really:
My notes:
About Pithing Needle, Surgical Extraction served in its place, so while it wasn't there in body, Austin was still siding with the spirit of Pithing Needle (I know you should know; I'm noting this for the passerby's that will wonder through this thread). Granted it's reactive instead of proactive, but it's also more permanent than Pithing Needle, too.
I'm not sure how much I like four Oblivion Stone main deck, but I see why he did it. It's for the same reason that I now main one Venser, Shaper Savant. It's relevance comes up so much that having it game 1 is worth making the room.
Speaking of Venser, there isn't any anywhere in this 75. I'm a cross between intrigued and disappointed (it's Show and Tell's Enemy is why). I could see the decision for Mindbreak Trap over it since Trap stops combo flat.
The more I play
Trinket Mage, the more I like it. Personally, I would have moved an Oblivion Stone to the side and done something to something else to make room for a pair of them because the utility of getting our most important artifacts is amazing. Just like how Eldrazi can solve anything the deck needs, our one drop artifacts do a lot of the same as well. But then again, unlike the Eldrazi, they aren't as necessary, so I'm going to credit it to a play style and meta decision.
This is going to be my most petty question and may just be me in my blind ignorance, but why is he running a basic Forest? I know that it's for the Green, but he runs more blue main board, and post board, he runs a LOT more blue. I think it should have been a Thespian's Stage, Island, or heck, even a Breeding Pool if he wants to up his dual count over four.*
*Eh... while I'll defend Island and Thespian's Stage, in the long run I'd likely run a Forest over Breeding Pool, but that Forest just stands out.
All that said, I like his deck a lot. He did a lot of things right, and the results speak for themselves (Top 32 is doing something right in my book, so Top 8... that's a major achievement). And even though I scratch my head on a couple of his choices, making it as far as he did just goes to show the flexibility the deck can engineer to where these varying choices and play styles are all viable. I look forward to mining Star City games for footage of him playing or if time doesn't permit, someone mining it up for all of us to watch.
