The developer’s 1.0 announcement adds Ascension card packs and 1,452 collectible cards. That number is not a claim that this site has 1,452 verified individual card records.

What is actually confirmed
The announcement describes newly illustrated Tetramon cards with fuller backgrounds. It also says that card stats, icons and Play Effect wording were adjusted in 1.0.
For that reason, pre-release diagrams are useful for understanding where information sits on a card, but should not be copied into a supposedly current stat database.
Decide what you are collecting
Choose a goal: a particular card, an artwork you like, collection progress or a deck-building need. Write down the target and your budget before opening stock.
Keep a separate record for a card’s appearance and its role in a deck. This helps when reviewing whether an attractive new copy actually changes your play plan.
Before trusting a list online
Check the version, whether an entry is a distinct named card or a print variation, and the origin of effect text. Be cautious when a page provides exact pull probabilities without a traceable source.
Our initial release does not publish Ascension drop rates, complete card counts by rarity or invented market prices. Add your own confirmed cards to the manual planner.
Good questions. Clear answers.
