Legacy advice/thoughts?

So I’m heading out to a legacy Open Trial tomorrow and I decided to go with this cool UR Delver list from GP Kyoto, anyone have any thoughts or suggestions?

4 Delver of Secrets
4 Young Pyromancer
2 True Name Nemesis
1 Snapcaster Mage
1 Grim Lavamancer

4 Force of Will
4 Brainstorm
4 Daze
4 Ponder
2 Gitaxian Prob
4 Lightning Bolt
1 Forked Bolt
3 Stifle
2 Spell Pierce

3 Volcanic Island
4 Flooded Strand
1 Polluted Delta
3 Scalding Tarn
2 Island
1 Mountain
4 Wasteland

1 Shattering Spree (couldn’t find a Smash to Smithereens)
2 Price of Progress
1 Pyroblast
1 Red Elemental Blast
1 Hydroblast
1 Pithing Needle
1 Grafdigger’s Cage
2 Surgical Extraction
1 Sulfuric Vortex
1 Electrickery
1 Null Rod
1 Echoing Truth
1 Flusterstorm

The meta I expect there is pretty varied, with a higher than normal amount of Miracles, Lands, and MUD Post, as well as some brews (Sam Black Zombardment???). Any thoughts on the numbers/contents and any suggestions would be greatly appreciated!
