As you can see this deck has no draw power or search power, so we rely on duel standby to give us the hand we need. This skill also gives us cards we can send to the grave with the effects of Vanguard of the Dragon and Wonder Balloons. Here's where this deck shines, because what it lacks in draw power, it makes up for by reusing cards in the graveyard. Most cards in this deck have effects that activates when sent to the grave or return cards from the grave.
If Darkstorm Dragon is in your hand, use Kidmodo Dragon as the cost for activating card effects. Discarding Kidmodo Dragon would trigger it's effect and allow you to special summon Darkstorm Dragon. But keep in mind that you cannot conduct your battle phase, nor can you special summon monsters except dragon-type monsters the turn you activate this effect.
Use the effect of Darkstorm Dragon to clear all spell/trap cards on the field by sending one of your face up spell/trap card to the graveyard. An excellent combo for this is equipping Supervise to Darkstorm Dragon to immediately gain his card effect, then send Supervise to the graveyard with Darkstorm Dragon's effect to destroy all spell/trap cards on the field, this would also allow you to special summon a normal monster from the graveyard by the effect of Supervise. Use this opportunity to special summon another Darkstorm Dragon.

Yeah but people need to realize that superalloy beast raptinus is only a support card, not the main focus of gemini, that way gemini can have a variety of build. You can even use magical merchant to fill grave and pick supervise then combined with butterfly to revive.
I actually wish they'd make a New Age version of Superalloy to make it more versatile...well, straight up useful. Like between it and First/Dragon, I'd pick 1st just because its better & a survivor even harder to summon than Superalloy.
