If you want to try a good combo with this card, play it using "Genex Undine" and "Genex Controller". When you Normal Summon "Genex Undine" , by sending 1 WATER monster (including a copy of "Genex Undine") from your deck to the Graveyard, you can add 1 "Genex Controller" to your hand, then use it for this card's effect to get rid of any powerful Special Summoned monster on the field like "Shooting Star Dragon", "Red Nova Dragon" , "Judgment Dragon", etc; or even your own monsters, and Special Summon "Genex Controller", ready for a Synchro Summon this turn. Also, "[enex Undine" and "Genex Controller" can work better with "Genex Power Planner", to create a similar combo like "Green Gadget", "Yellow Gadget" and "Red Gadget".
This card can be useful in a "Elemental HERO" deck; there's enough Normal Monsters in the archetype to make it worthwhile. Though it would be better to just use Miracle Fusion and Polymerization, instead.
