Does Perplexing Tempest reduce forced movement, and does it slow the player who played it?

Question

Accepted Answer

No to forced movement, because forcing a card is not moving it, so Perplexing Tempest reduces only regular movement. It affects both players while it is in play, but it is played after your Move phase and removed before your next one, so in practice it does not slow the player who played it.
