I think what you've labelled as your early control is mostly mid-to-late control. Hunter's Marks need another damage source to finish something off. Steamwheedle Snipers usually get killed before you can use the power if you play them before turn 4, Annoy o Trons can only remove things when combined with Hunter's Marks or when up against Face Hunter. Freezing Trap works early, but it also works late. Ditto for Hunter's Mark. I'd expect early control to look more like Arcane Shot, Explosive Trap, that new Hunter version of Dark Bomb whenever it gets released, Glaivezooka, and Eaglehorn. Probably Mad Scientist to dig for free Traps while trading to remove something. Probably need Animal Companions too, they're really too good not to include in any Hunter variant and you definitely need more beast synergy if you want to run KoB and Houndmaster.
