Summon Goyo Defender x3, then summon 1 lv4 extender, voila. If you draw Cyber-Stein, use Stein pay 5k ss D-Hero Dangerous, use Dangerous discard 1 send Malicious, use Malicious ss another one, make Isolde, use Isolde send psychic equip ss Renaud, use Renaud add psychic equip, make Reprodocus using Renaud+Isolde on top of Stein, make Stein psychic-type, continue as usual. Another key point is
always summon Stein below EMZ for Reprodocus target.
Pros: Yep
Cons: Fragile
