As per Multicaster view #12, the HDT API is currently reporting secrets played from deck by the cards below as OnPlayerPlay rather than OnPlayerDeckToPlay

Affected Cards

• Mad Scientist
• Inconspicuous Rider
• Sword of the Fallen
• Bellringer Sentry
• Phase Stalker

Have modified both player and opponent code for consistency although I suspect the opponent code is never reached.
