Frozen Emerald Serpent

Don't read the Icejade lore. You will cry. Instead, crush your enemies with this deck!  *+~ --/ᐠ｡_｡--ᐟ\

Basic info: Ran Aegirine = Instant Gymir Aegirine. Normal Aegirine → Normal Cradle → Ran Aeg = Gymir. Easy, right?

OR: Deep Sea Diva → Guitars and make sure to banish your enemy's cards. Need spell defense? Double Guitars to make Dragite. REALLY need Aegirine? Double Diva to get Donna and give your opponent a card to get the best girl out of your deck. THEN, once you don't need Aeg anymore, make Chengying or Gymir, or if you're playing in Master Duel, you can create an invincible infinite Baronne - Prima Donna loop!

Always make sure you have a field spell out, just in case you have Icejade Curse out or Kosmochlor in your hand. Oh, yeah. Those two. If you have both out, along with Icejade Cenote Enion Cradle, you make it so that your opponent can't activate monster effects on the field at all! AHAHAHAHAHAHAHAHAH!!!

Make Egyptian God Slime if you're feeling particularly dyspeptic about stuff getting messed with, Coral Anemone if you need to recycle Aeg or Guitars, and White Aura Whale if you need to bulldoze some things.
