UW Delver Construction and Sideboarding

[OtosReborn]

Okay, so I have been out of the standard meta for a long, long time, and I finally want to get back into it, and I see UW Delver putting up good results.

I was thinking of some variation of GerryT's list from the recent SCGO.

Deck
Artifacts 2 Sword of Feast and Famine Creatures 4 Delver of Secrets 4 Restoration Angel 4 Snapcaster Mage Instants 2 Dismember 2 Gut Shot 4 Mana Leak 4 Vapor Snag Legendary Creatures 4 Geist of Saint Traft	Sorceries 4 Gitaxian Probe 4 Ponder Basic Lands 9 Island 1 Plains Lands 2 Cavern of Souls 4 Glacial Fortress 2 Moorland Haunt 4 Seachrome Coast	Sideboard: 2 Ratchet Bomb 2 Consecrated Sphinx 4 Phantasmal Image 1 Divine Offering 1 Amass the Components 3 Timely Reinforcements 2 Ghost Quarter

No thought scours? No phyrexian metamorphs? No sword of WaP? See, I don't even know what's good. I can only assume Sword of FaF is for the green aggro and to protect against dismember. I know why he plays 4 Resto Angels over 3, since they are insane in combat, against spot removal, and with Snapcaster.

If someone can explain this deck to me, thanks a ton. Also, how do I sideboard? I know Images are for legendary dudes or pains in the butt (Huntmaster, maybe geralf's messenger?) but, what do I take out? If someone can provide a complete sideboard guide, and why you board that way, thank you so very much. (I don't even know what to do with timely, amass, or sphinx) I guess Ghost Quarter must be for Wolf Run or something.

You should probably ask this question elsewhere, might be easier to find guidance.
