What is antiscion

Antiscion is an astrology term, not a tarot one: it's the point exactly opposite your Ascendant — the deepest point of your 7th house, sometimes called the "anti-Ascendant." If your Ascendant is the east horizon (where you meet the world), the antiscion is the far side of the sky, facing the part of the world behind you and the partnerships/other-people side of your chart.

Plain version: a point on the ecliptic band located by taking the degree rising on your eastern horizon and moving exactly 180° along the zodiac.

Where it gets used:

• Astrogeography / relocation — mapping where on Earth your Ascendant (and the antiscion, your Descendant) would sit on the horizon. Astro-cartographers draw an "antiscion line" through places where your partner/relationship point rises; some relocation traditions treat living on that line as significant.
• Hellenistic astrology — the 7th house was called the "House of the Goddess," and the antiscion, its lowest degree, was read as the most hidden and consequential part of partnerships.
• Ordinary modern natal charts rarely feature it; most people meet it through relocation work or older texts.

Two honest limits: I found no entry for it in this assistant's own glossary files, so this is the standard definition as I know it rather than a quoted reference, and I have no chart of yours here — if you want it placed, that needs your birth date, time, and city, and it would be an astrology reading rather than a card draw. If you actually meant a different term (antiscion vs. ascendant vs. antiscope are easy to mix), say which and I'll re-answer.
