All I said was that I figured those were the best Slivers in my opinion, and those were the abilities that best abused the multicolor nature (differentiating the deck's abilities from an all-red for example).
However, a Sliver deck can be very versatile, and that was the other side of the old Sliver discussions on Beyond Dominia.
You can turn it completely around and use Lightning Bolt and Incinerate instead of counters, and that's quite aggressive. You can use Memory Lapse as your counter, since that delays the opponent and gives you another attack. When I said Hibernation Sliver worked with Force of Will neatly, I didn't mean go Counter-Sliver; Force of Will is a great beatdown support card since you stall him without missing a beat. Round out your burn with Duress since you're using Acidic Sliver, and you can have a mean little aggressive deck.
If you're fighting burn, you should have a shot at beating him to the punch since your cards aren't one-shots, though Victual Sliver does help. Hibernation Sliver still helps beatdown since you can trade 2 life for one of his 2/2 or 3/3 creatures.
Sliver Queen is good later on for this kind of deck and it can win games. All I said was that drawing 3 or 4 in your opening hand isn't going to get you anywhere.
Finally, playing with Slivers is, by nature, playing some kind of control. Your creatures are weenies too, but slower and less powerful than the mix of creatures and spells available to mono green and mono red.
If you find an opponent more aggressive then you, won't you have to take advantage of your incredible flexibility and do a little controlling before the final push? And that flexibility involves versatility, but it also involves a little consistency in the Slivers you'll get.
