Unstable Unicorns - what is the definition of "effect"?
Blinding Light treats your unicorns as if they have no text on them at all, except &quot;Basic Unicorn.&quot; So if the Annoying Flying Unicorn is sacrificed or destroyed in your stable, it just gets discarded like any other dead unicorn. When you play a unicorn into a stable that already has Blinding Light, it does nothing – just like a Basic Unicorn.
When I looked up Blinding Light, I found this image, which has much less ambiguous text:

No mention of &quot;special&quot; effects, just all Unicorn card effects, i.e. all of the text at the bottom of a Unicorn card. (If your Unicorns were all Pandas, they would be unaffected by this card.)
