SO Im going to the Philly Open tomorrow and am starting to get worried that Eldrazi is going to flood the metagame there. I have literally 0 experience against the legacy Eldrazi deck and no time to try to test the match-up. Does anyone know if shardless even has a chance against this deck? Should i warp my sideboard slightly to hedge against the deck? I feel like my match-up would be terrible but idk. This is my decklist:

Creatures:

2 Baleful Strix

4 Deathrite Shaman

4 Shardless Agent

4 Tarmogoyf

Planeswalkers:

1 Jace, the Mind Sculptor

2 Liliana of the Veil

Instant/Sorcery:

4 Abrupt Decay

3 Ancestral Vision

4 Brainstorm

4 Force of Will

2 Hymn to Tourach

1 Maelstrom Pulse

3 Thoughtseize

1 Toxic Deluge

Lands:

1 Bayou

1 Creeping Tar Pit

1 Forest

2 Misty Rainforest

4 Polluted Delta

1 Scrubland

1 Swamp

2 Tropical Island

3 Underground Sea

4 Verdant Catacombs

2 Wasteland

SIDEBOARD:

2 Disfigure

1 Golgari Charm

1 Grafdigger's Cage

1 Hymn to Tourach

3 Meddling Mage

1 Nihil Spellbomb

1 Notion Theif

1 Null Rod

1 Pithing Needle

1 Sylvan Library

1 Toxic Deluge

1 Umezawa's Jitte

Maybe removing some combination of Notion theif, needle, Library, Jitte, Charm....for another white source and some swords? Idk if thats worth it..any suggestions?
