Main strategy is to put 4 bodies on the field, then:
-link for beat cop, elpy and pisty
-Bring REDMD with pisty, revive a rokket (usually tracer)
-Link REDMD, pisty and beat cop to bring Borrelguard or Borrelsword
-Bring back REDMD with pisty and revive another lvl 4 rokket
-Link REDMD and Pisty into Dillingerous, Link both rokkets into quadborrel.
-Use quadborrel's effect to pop Dillingerous, it revives 2 rokkets and then Dillingerous revives itself when a rokket is special summoned.
-Link Dillingerous and Quadborrel to bring Unchained abomination, Synchro summon Borreload Savage.
-If you are able to summon a 5th body, make sure to leave anesthrokket dragon on the field for the extra negate, or maybe leave silverokket to destroy one of the oponent's extra deck monsters.
If you open with dragon's mirror, you can choose to leave Borrelguard and Borreload furious (instead of unchained abomination) for the broken combo. Starving venom is in the extra deck because we can easily bring it out with 2 rokkets, and it can win you the game alone.
Crusadia draco helps you put that 4th body on the field. If you are only able to bring out 3 rokkets, no problem! Link summon beat cop, pisty, and special summon Crusadia draco to the free zone that beat cop points to, then use it to summon elpy.
Remember that, in case you need it, you can revive borrelsword or borreload by fusion summoning borreload furious, then destroying it with his own effect, and banishing it from the graveyard.
