Help me with my Pokemon Black Team!

[Gotta Catch 'Em All]

Hey everyone, so I've just finished the Elite Four and I've been buffing my Pokemon a bit in the Challenger's Cave, as well as against some of the trainers on the way to Black City. I feel that my Pokemon team are capable, but I do believe some improvements could be made.

The problem is, I'm unsure *What* improvements, so I'm looking to you guys to give me a hand! Here's my team as it stands, please advise new moves I should teach my Pokemon, or maybe some new Pokemon I should look into bringing into my party. Thanks, everyone!

Virizon - Lv. 52 (I feel I may have messed this guy up a bit. Need some serious advice here as to the future of him):

• Sacred Sword
• Flash
• Giga Drain
• Strength

Victini - Lv. 55

• Thunderbolt
• Brick Break
• Flame Burst
• Zen Headbutt

Excadrill - Lv. 56

• Drill Run
• Shadow Claw
• Rock Slide
• Brick Break

Reshiram - Lv. 53

• Fusion Flare
• Fly
• Dragon Claw
• Rock Slide

Samurott - Lv. 50

• Surf
• Aqua Tail
• Dig
• Slash

Haxorus - Lv. 50

• Dragon Pulse
• Strength
• Brick Break
• Bulldoze

Thanks for all your help, everyone!

Suppose a few changes could be made

Virizion
Item: Big Root
-Sacred Sword
-Quick Attack
-Work Up
-Giga Drain

Samurott - Lv. 50

• Surf
• Aerial Ace
• Dig
• Aqua Jet

Yeah, the ingame skills of opponents will make Dig useful.

Haxorus - Lv. 50

• Dual Chop / Dragon Claw
• Swords Dance / Dragon Dance
• Brick Break
• Bulldoze / Shadow Claw

Haxorus should not be using any special attacks. Except maybe Surf or Incinerate.

Depending on competitive you are planning to go (just ingame, battle with friends or random WiFi matches), you could think about nature and IV breeding and EV training.

Thanks for everyone's replies.

@ Pwnyta, Dig was actually more so that my Samurott had a different element besides Water in his arsenal. Also, the ability to be able to leave caves without needing an Escape Rope is useful. But I will take your suggestions on board.

I looked at your team and you had 2 Fire-types, Victini and Reshiram. I best recommend you dump Victini 'cos it has way more weaknesses than Reshiram. For a non-Electric-type Thunderbolt user I recommend a Gothitelle since you're playing Black 'cos I plan to get one when I play Black.
