I usually run 1 Chalice of the Void, 1 Engineered Explosives, 1 Executioner's Capsule, 1 nihil spellbomb, and 1 Darksteel Citadel. Against most matchups, chalice @ 1 is devastating. Some matchups really need 2 cmc or 3 cmc cards enough that you wouldn't mind shutting off your own cards of that cost just to spite them. Most of these can blow out specific decks (boggles vs EE, Executioners helps a ton against twin), and your sideboard can contain things that make it even more devastating, like Grafdigger's Cage and Elixer of Immortality.
Adding chalice makes 1 drops less effective. I think Thoughtseize is still worth playing but things like Serum visions less so. My reasoning for that is that thoughtseize are going to disrupt your opponent's plays early, and make room to force through counterspells, which are the times where chalice is less effective (they would have countered it probably anyway). I'd add 4 of the temples of scrying, maybe even 1 more just so EE has a chance of hitting 3 later on, as pseudo replacements of Serum Visions that don't get hit by chalice.
