"Hidden Armory" is a very useful card for digging out one equip spell card in your deck or graveyard and add it to your hand by sacrificing one card from the top of your deck along with your normal summon or set for the turn."Supervise" is a card that will give your gemini monster its effect and if it has been sent from the field to the graveyard you can select one gemini monster from your graveyard and special summon it into play."Mist Body" will keep your gemini monsters in play longer to give you the chance to activate there effects if needed...or you could stall for more time. ^_^ "Divine Sword-Phoenix Blade" will combo very well with the effect of "Evocator Chevalier" which will allow you to use his effect multiple time times in the duel at the cost of removing two warrior monsters in your graveyard from the game to bring your sword back to your hand and you can force its effect even faster using "Field Commander Rahz".
