Use Cyber Dragons and Galaxy Soldiers to summon monsters, e.g. discarding Cyber Dragon Herz to special summon Galaxy Soldier, activating Herz's effect adding a Cyber Dragon to hand and activating Galaxy Soldier's effect adding another of it from deck to hand, and then do the same again with Cyber Dragon instead of Cyber Dragon Herz. Then you can choose to summon Predaplant Verte Anaconda to summon Dragoon, or you can summon Cyber Dragon Nova, converting it into Cyber Dragon Infinity. Either way... RIP for the opponent. You can work the other combos out for yourself.
