Astronomical

The Astronomical archetype is an archetype debuting in Yu-Gi-Oh! Xenon. It consists of monsters created from astronomical symbols and zodiac signs.

This archetype focuses on swarming the field and having monsters in the Graveyard. All monsters in this archetype share text that includes two effects: "You can Special Summon this card (from your hand) whenever you Special Summon an "Astronomical" monster. If a face-up "Astronomical" monster is destroyed while this card is on the field, the battle damage becomes 0." (Yes, another archetype that is overpowered because it'll be used by the enemy.)

The archetype is formed so that whenever you control 2 or more "Astronomical monsters", you won't take Battle Damage. This does work well due to the monster's original ATK being 0. All of their effects, however, increase their ATK/DEF. Some have effects that kind of match the planet they are, or whatever god/goddess they are. All besides Earth, which has an effect pertaining to the apocalypse, destroying everything on the field.

The second part of this archetype, the "Astronomical Zodiac Symbol"s, all have a base of 2000 ATK, and all have 0 DEF except for Capricorn, which has 1400 DEF. "Astronomical Zodiac Cycle" must be played before any can be Special Summoned, starting with Aries, and then ending with Pisces.

"Skill Drain", and other effect-negating cards, obliterate this archetype. Also, any cards that prevent Special Summoning, such as "Vanity's Emptiness", lock this archetype down. Because of that, there are support cards for this archetype that aim to lockdown the opponent to prevent any such cards being activated.
