"Quick Junk Doppel" Deck 2015

Playing

If you drop the level stealer on GY early in the game, it will be easier to sync later. With Accel Synchron's level change and GY Fertilization effect, Jet Synchron can be sent to GY for further Synchro Summons, and level changes can lead to various Synchro Monsters.

Weakness

Weak against 《Thunder King Rai-Oh》, Wonfu, Steelswarm Roach, etc. It is good to put Photon slasher etc. as a countermeasure.
It's vulnerable to interference such as traps due to being too conscious of its development, so it might be a good idea to include 《Royal Decree》or Cyclone.

Customize

Since the defense is weak, I think it will be stable if you remove Orion and insert Swift Scarecrow or Goes.
