Flip effect, so you can manually flip summon if your opponent does not attack it.
Sending an unwanted card will ensure that you get your essential ones before your last turn.
Low attack and defense. Will not survive an attack.
The card that is not selected from the 2 shown will get sent to the bottom of the deck. If you don't have ways to search from, or shuffle the deck, the unselected card will stay on the bottom of the deck.
Your opponent can also see the 2 excavated cards.
If you set this card with no other monster and your opponent has at least 1, you will take damage on the next turn since crystal seer will not survive.

Works well in many farming decks, including unhappy girl with holy guard skill. After locking all 3 monsters your opponent controls, you can flip summon crystal seer and attack into your opponent's monster to destroy it.
When you only have 2 cards left in your deck, you can flip summon to see what they are, and take the one that you need before you run out of cards.
