Be a bird!
In the lane, try to position your soldiers between the enemy's minions and the enemy champion. This way you can use them both to last hit and to project threat onto your lane opponent.
Be careful about putting down both of the soldiers stored by Arise! Unless you're going all-in, always have a soldier in your back pocket if you need to escape over a wall or if you misposition your other soldier and need damage now.
Think of Emperor's Divide as a defensive ability first and foremost. Use it when the enemy engages on you or your allies. Remember that your team can walk through the soldiers summoned by Emperor's Divide and use this to your advantage when enemy melee champions engage on you.
