The facts on the card

The card carries these facts from its Wikipedia article.

It approximates the value of a function at an intermediate point within the local axial rectangular prism linearly, using function data on the lattice points.
Trilinear interpolation is frequently used in numerical analysis, data analysis, and computer graphics.

Why it is Uncommon

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Trilinear interpolation article was read about 18,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 55 and blocks with 20: each hit it takes is cut by 8 %.
