Analog Man provides the effect to switch attacking's target to a LV6 Digimon with Machine in its trait. This makes the new Machindramon deck becomes more competitive with other decks in current meta. With Analog Man, we also gain more memory and draw more in "starting of main phase", so the draw power is also better than old version.
(By the way, it would be troublesome when dealing with blue because they might bounce tamer back to hand)
The BT11 Machindramon gives an interesting tech for the deck. Not only searching for the right card to use, but also allow that card to be put on hand or to become a digivolution source for this Digimon.
When this Digimon is deleted, if we have Analog Man in play, we can summon 1 Machindramon deck for free by placing an Analog man card to bottom of the deck. The EX1 Machindramon would be a good candidate to be called, and can gain back maximum 5 memories if we able to put 5 lv5 "Cyborg" under its digivolution source.
The EX1 Machindramon deck can gain "rush" and "blitz" in the turn it appears if we use the option card "Heavy Machine Digimon's Advance!!" on all the LV6 Machindramon and Chaosdramon. So now we have the chance to decide our game: add more "security attack+1" or "piercing" or "trash opponent's security" or "delete opponent's tamer" or "attack active Digimon" or add DP. If we can clear the opponent's security with the EX1 Machindramon, we can play another LV6 Machindramon or Chaosdramon to win the game because it also have "rush" and "blitz" thanks to the option card we used earlier.
