Use this card to return "Cyberdarks" to your hand to recharge its abilities and special summon "Armageddon Knight" in defense mode to send "Hunter Dragon" to the graveyard for your "Cyberdark" to target next turn.
An excellent candidate to Special Summon in this deck type would be "Gemini Summoner". Not only can it avoid destruction by battle one time, but it can let you summon a relieved Gemini monster back to the field during your opponent's end phase and launch a comeback with "Dark Valkyria's" monster destroying effect or Synchro Summon using "Tuned Magician".
This card works quite well in "Fortune Lady" decks, as by sending one "Fortune Lady Light" on the field to summon "Fortune Lady Water" while having one other "Fortune Lady" monster on the field, this allows you to Special Summon a second "Fortune Lady" monster from your hand, thanks to "Light's" ability, which is helped by "Water's" ability to draw two cards, for possible swarming.
This card also works well with Mist Valley cards. One example would be using this card while you control a face-up Divine Wind of Mist Valley to return a face-up Mist Valley Thunderbird you control to the hand. Thunderbird will Special Summon itself, you can Special Summon a free Level 4 monster from your hand, then use Divine Wind's effect to Special Summon another monster. Here's an example combo
