Get Destiny HERO - Plasma in your hand by using Reinforcement skill. You might summon Troop Dragon and Bubonic Vermin in face-up ATK position to decrease your LP at least 1800 to activate the skill.
Special summon Destiny HERO - Plasma by tributing Troop Dragon, Bubonic Vermin, or Cosmic Compass. Use the effect of Destiny HERO - Plasma to increase its ATK.
Once you summon Destiny HERO - Plasma, Alexis's monsters' effects are negated, meaning Destiny HERO - Plasma won't be destroyed or sent to the graveyard by the effects of her Cyber Angel Dakini or Cyber Gymnast.
If you don't have Desert Twister, add one more Secret Pass to Treasure. The first one will be negated by Alexis' Spell Shield Type-8, then the second one will be successfully activated.
Dark Paladin (7-8k)
Special summon Dark Paladin in DEF position as soon as possible using skills like Balance and Restart. Dark Paladin's effect can negate the activation of any spell card by discarding 1 hand, meaning Alexis' can't perform ritual summon. Note that Alexis uses the effect of Cyber Gymnast to destroy your Dark Paladin if it is ATK position.
Use King of the Swamp depending on what you need. You can send it to the Graveyard to get Polymerization or use it as a Fusion Substitue. It's recommended to have more copies of this card and replace other Fusion Substitute monsters.
Labyrinth Bulder doesn't work anymore she attacks directly regardless to force you to use Dimension Gate to attack with the monster you used Massivemorph on. She will attac directly now matter what. :(
I assume you have no problems summoning Dark Paladin early in the duel. Choose your least required card and replace it with Fiend Megacyber (if you have a copy). That frees up one fusion substitute, dark magician and polymerization that you can use as discard cards. You will have to destroy machine angel ritual, machine angel absolute ritual, ritual sanctuary and big bang shot.
Good advice, but unfortunately my luck with packs is terrible. so i dont have a copy of fiend megacyber to use :/ tried running a d plasma deck as well but with my last 3 runs worth of keys i kept bricking. starting to feel like konami's way of balancing cyber angels is to just prevent new people from getting them in the first place
The Dark Paladin deck is actually working for me. I have just replaced Dark Flare Knight with Fiend Megacyber. I kept finding that Alexis blocked polymerization or secret pass, so I did away with both. By the time the last turn comes around, she has three monsters on the field so megacyber works.
