Your pretty close, couple more cuts and your there
The deck has two main goals: to build a large army of human creatures, and to pump the army of humans through dozens of anthem and +1/+1 counter effects, allowing you to attack with a massive army of huge creatures
To have two commanders, both must have the partner ability or corresponding "partner with" abilities as the game begins
