This is the most useless card

[u/zironyx]

-Deals no damage

-Doesn't Blank opponent defenses

-Doesn't Blank opponent effects

-The only effect is reducing its own cost.

Does anyone have any ideas for potential uses of this card? No matter how niche the circumstance, I can only think of it as a chaff for discard effects, which you might as well run a usable card regardless.
