Notes & Combos
Ok... so this might look strange but let me explain. This isn't your typical Alien Ogdoadic. It does follow the same flow basically so it isn't easy to pilot but basically Nunu and a discard gets you the entire alien lock. By main decking 1 kid and 1 stealthbuster, you get the end board of Slicer Plus Alien Kid to stun all their special summons
The adventurer is a 1 card engine that provides a negate and with the equip spell of choice, you get an extra 500 attack reduction to keep your alien kid healthy. You also recycle it every turn with Aleirtt hence the 2 copies of Fateful Adventure. Many of the combo pieces are interchangeable, and if you open any 2 pieces, most of the time you can get the alien lock with savage dragon equipped with the alien link 2. This is extra neat because if the link is destroyed while equipped, you still get to soul charge for every 1 counter on the opponent's field, which alien kid will be flooding their whole field, also stealthbuster in the GY allows you to pop any threat if they get past your field
The ogd engine in the grave can facilitate Draglubion OTKs easily. Remember the Reptilianne link 2 doesn't lock you into reptiles UNLESS you search, so you can use her for the attack drop and then offer her away for an 8 and just rob the game with otks. This deck is good going first and second and can play around negates but its far from linear.
Slash Draw and Bubble Man are my techs of choice. This deck topdecks and plays from the GY on turn 2 and on so bubble man is tons of mileage. you can easily mill your hand to the GY, then SS it and get a body AND a plus 2, or bait a negate and still do your full lines even if you open with it, it's an extra body for Abyss dweller or getting savage dragon on top of the lock. Slash draw can rob games on turn 2 and loads your GY and allows you to recycle used spells and 1 of cards to facilitate plays. This deck does a lot more then mentioned here and you wont really understand all of the choices until you mess around with it.
Hindsight though, you can play through anything that isn't named Maxx C so I would make room for 3x ash and possibly a psyframe package.
