Chalice is, first and formost, great against Storm. Is that relevant? Not very. Storm will never be more than 10% of the field. What else is it important against? It has limitted playability against Delvergoose decks since they live and die by their 1-drops, but they'll usually have a counter to answer Chalice and Goyf to play around it. Plus, if you keep a Chalice hand against them they just might blind-flip a Delver T2 and just cruise to victory with it anyway. I don't think Chalice is very important, but it is a card that can steal games against the right deck. One of the advantages to playing Chalice is that your opponent will probably side-out some counterspells against you, since Goblins has a way of playing through those (Lackey, Vial, Cavern). So Chalice probably has a better chance of resolving G2 than you'd initially think.
I was playing Pithing Needle just to see how effective it would be. I discovered that it was only OK in the MUs I faced with it, but not over-powered. Against Junk it shut off Top, but then his draws were good enough that he eventually got a Deed, so Needle was kind-of a wash. And that's a real problem with a lot of SB cards. Every SB card takes 1 goblin out of your deck, so you can't really side in too many cards if they're not going to make a big impact on the game.
Really, as of right now, there is only 1 card I really want in my SB, and that's Rest in Peace. I've been waiting and waiting for a card that can shut off Thresh and RiP is that card. My only question is whether to run 3 or 4. I want to run 4, just because it's so powerful, but since it's a little slow a faster piece of GY hate might also be necessary, so maybe only 3 RiP +1 Surgical or whatever.
Otherwise, Seal of Cleansing is a great, proactive answer to Control, Equipment, and SnT combo, which is another reason to run W.
Between Thalia, RiP and Seal it seems like W has an awful lot to help Goblins in an awful lot of MUs.
That's enough from me for now. I'm off to vote. Merica.
