I'm going to a small Legacy tournament tomorrow afternoon (unknown meta), and planning on the following list:
//Mana
4 City of Traitors
4 Ancient Tomb
4 Chrome Mox
3 Seat of the Synod
6 Island
//Creatures
4 Sea Drake
4 Serendib Efreet
4 Cloud of Faeries
3 Trinket Mage
2 Solemn Simulcram
//Blue Non-Creatures
4 Force of Will
3 Thirst for Knowledge
3 Psionic Blast
//Artifacts
4 Chalice of the Void
4 Sword of Fire and Ice
3 Umezawa's Jitte
1 Tormod's Crypt
//Sideboard
3 Misdirection
3 Binding Grasp
3 Energy Flux
3 Pithing Needle
3 Sea Sprite
The maindeck Crypt is there in place of the usual Needle to combat graveyard-based strategies (e.g., any Tier 1 deck other than Goblins/Affinity), as it can quickly be Maged up when needed and won't get eaten by Chalices. The SS are mostly untested, but from what I've seen of them, they've been Lay of the Land and Moat rolled into one (and trade with Piledrivers, giving me a non-Equipment out against it).
I'm not sure what to cut from the SB to make room for 2 more Crypts. I might go -1 Grasp, but Grasp is too useful against opposing aggro decks and can't easily be tutored for.
