How about this:
I made a Ranger multiclass Rogue who is level 2. I took the two weapon build.
My tactic is to use "unbalancing parry" to gain combat advantage then attack using "evasive strike" and add my sneak attack damage and Hunter's Quarry damage for a single, face-melting blow...
Unbalancing parry:
Encounter ✦ Martial,Weapon
Immediate Reaction Melee 1
Trigger: An enemy misses you with a melee attack
Effect: Slide the enemy into a square adjacent to you and
gain combat advantage against it until the end of your
next turn.
Evasive Strike:
Encounter ✦ Martial,Weapon
Standard Action Melee or Ranged weapon
Special: You can shift 4 squares either before or after the attack.
Attack: Strength vs. AC
Hit: 2[W] + Strength modifier damage
Sneak of Shadows:
Prerequisite: Dex 13
Benefit: You gain training in the Thievery skill.
Once per encounter, you can use the rogue’s Sneak
Attack class feature.
Since the CA lasts till the end of your next turn and you can choose to add sneak attack damage after the damage roll, you have a second chance to use it if the first attack fails... that is if your like me and don't want to worry about sneaking around to get CA
