Heimerdinger, Inventor

Q: When I played <<The List>>, I named the “Poro” tag. If I activate <<Heimerdinger Inventor>> using <<The List>> ability, can I reduce a “Poro” unit’s might?

Rules for Context - 395.

A: No.

The List’s activated ability is a linked ability with the list’s passive ability that names a tag. Heimerdinger only copies the activated ability and not the linked passive ability. “The named tag,” in the copied ability will be undefined, and thus no legal target will be able to be chosen.
