Subject: A Good Sliver Combo
A great Sliver combo is this.       

1. Play a Ward Sliver and pick protection from opponents color (strongest color if there are more than 1).

2. Play Shifting Sliver (Slivers can't be blocked except by slivers). 

3. Play Essence Sliver (Whenever a Sliver deals damage you gain that many life points).

Now, you can keep on attacking, they can't block you, you gain a lot of life, and you can block them and not die.
