Hey. I got a tournament coming up on June 7th at my hobby store and like the title says its a doubles tournament with 1000 points for each team member. The rules are one HQ and two troops as usual, but we all agreed that we can only take one HQ for every army so bear with me on that, and only allowed 0-2 fast attack, heavy support, or elite choices. I am partnered with my twin bro, who is playing steel legion imperial guard and he has:

Doctrines:
*Carapace Armor

*Command Squad:
-w/Senior Officer w/BP, PW
-(3x)Plasma
-(1x)Master-Vox
-Commissar w/BP, PW
-Chimera w/multilaser, hull-mounted hvy. bolter, extra armor

*Anti-Tank Team:

-Squad Alpha
-w/Sergeant w/LP, CCW
-(1x)Plasma
-(1x)Vox
-(7x)Guardsmen w/lasgun

-Squad Bravo

*Leman Russ Battle Tank:
-w/Battle Cannon, hull-mounted lascannon, hvy. bolter side sponsors

Total: 997 points

As you can see, he has a lot of firepower,and enough anti-tank weaponry to tackel anything in 1000 points, so I've come up with 3 different army lists that I could use in the tournament and I was wondering which one would be the best to run with this Imperial Guard Army list.

List #1:

*Emperors Champion:
-w/accept any challenge

*Crusader Squad #1: (w/Emperors Champion)

-w/(1x)PF, BP
-(1x)melta
-(8x)BP, CCW

*Crusader Squad #3:

total: 1000 points

Please tell me which one you think is best suited to be with this guard army and thnx for your time. And if you are wondering, the plan is for us to move quickly towards an enemy if assulting, or him forming a battle line while I either support with counter attacking and adding some firepower or have him stand and shoot while I move up and assult on one flank and drive the enemy back,and as far as I know at the moment, we will be playing a eldar and thousand son team, a nid and other templar team, and a chaos bike and Marine or Tau team.
