Monsters that are destroyed is not a big disadvantage, with the help of Woodland Archer, you can easily draw your desired useful gemini monster for a specific situation. Blazewing Butterfly is one of the key card of this deck, it can easily summon your gemini monster as a "effect" monster from your graveyard.
By equipping Big Bang Shot to your opponent's monster and activating Darkstorm Dragon effect, you can clear your opponent's field and make a direct attack.
Phoenix Gearfried can serve as a rescue card that can easily turn the tide once successfully summoned as a effect monster, it has the effect that can easily fill up the board with monsters from your graveyard. If this card's effect is active, it can hold your opponent from recklessly casting spells.
Gemini monsters are all normal monsters with effects that can be activated by normal summoning them. To use their abilities, you will have to use up your normal summon by selecting the card when they're face up on the field and normal summon them. You can only normal summon 1 monster per turn, if you use that to get a monster to the field then you will have to wait until next turn to do it.
Sending them to the graveyard
Since all of them are normal monsters at first, you can use Order to Charge to deal with any monster. This will send them to the graveyard, which will only help you later when you have Woodland Arher. Alternatively, you can also use Enemy Controller to tribute your own monster to send them to the graveyard, or use it to protect your monster so you can normal summon it later.
Using them from the graveyard
Woodland Archer can be special summoned when you have at least 2 normal monsters, and since all gemini monsters are considered to be normal monsters when in the graveyard, this means that any monster in the graveyard will benefit the archer. The other use for monsters in the graveyard is to revive them by using Blazewing Butterfly to get any gemini monsters back on to the field.
Cards that let you special summon monsters will allow you to use 1 normal summon per turn to activate a monster's effect immediately. Cards like Regretful Rebirth for Gemini Scorpion can make you special summon a gemini monster from your hand.
Super Double Summon
Super Double Summon is a quick-play spell, which allows any gemini monster to have it's ability instantly. It's not recommended to use Super Double Summon during your turn to attack the enemy, since most players often have defensive cards like Windstorm of Etaqua or Sphere Kuriboh. Use this to destroy enemy monster during their turn or use it for Blazewing to revive any gemini monster with it's effects already available.
Man... with all these new cards Gemini still suck. You have to put in so many spell cards just to get your monsters rolling and you are still very easy to lose due to crappy backrow. Other than Duel Standby switcheroo is a must for this deck. I can't imagine how aweful this deck will become when switcheroo got nerfed.
This sample is close to what it should be. Interdimensional transport, branch, a pendant are what's missing. Use only one fusion sage. This deck has already been getting KOG. This is the new top tier meta deck
Toss in wonder balloons. That should be interesting.

I use Monster Reincarnation in my deck. Lets me dump Darkstorm/Gearfried or a spell/trap card for Blazewing from the Graveyard and vice versa. Then its easy to use Woodland to get Blazewing from there.
