A few good combinations -
  Myr Turbine + Mirrorworks
  Myr turbine + Eldrazi monument
  Mirrorworks + Steel Overseer
  Sylvok Lifestaff + Myr Turbine
  Ornithopter + Pennon Blade
  Ornithopter + Steel Overseer

The principle is to try and get Myr on the table as quickly as possible and start attacking for 1 damage each time (not a lot but it builds up quickly).

As the game progresses, add a Myr Galvanizer or Steel overseer to boost the 1/1s and continue attacking.

If the opponent is still alive by the time you have the battlesphere in your hand, then play it and finish them in the next turn or equally using Eldrazi monument to make your 1/1 Myr flying and indestructible.

Always try to have either a Soul's attendant or Myrsmith on the table, and in the best situation, both.

Bounce Sylvok Lifestaff and Pennon Blade around your 1/1s and slowly gain health (Always attack with the equipped myr as you will have plenty more soon enough)
