Within the Card node, it is possible to make alterations to the card geometry itself within the Deform tab, using either Bilinear or Bicubic operations.
It has been discovered that if you attempt to subdivide by UV within either operation, if the input is as an image, this image will be distorted to match the UV coordinates in addition to the geometry.

Steps to reproduce
1) Within a new Nuke session, create a Checkboard node
2) With the Checkerboard node selected, create a Card node that is connected to the Checkerboard node
3) In the properties of the Card node, in the 'Deform' tab, press the 'UV Subdivide' button
Result: The input texture is distorted to the subdivided UV coordinates
Expected behaviour
The input texture should not be subdivided based on the UV coordinates, on the geometry
Actual behaviour
The input texture is distorted, along with the geometry
Workaround
An alternative would be to project the texture using a Project3D or UVProject node. This will allow you to modify the geometry without altering the texture.
