Silent-Blade Oni doesn't allow casting a card from opponent's hand
n a commander match I hit a player with Silent-Blade Oni, then I chose a card from his hand that I wanted to cast. The game told me to click the card I chose in order to cast it but the card did not appear anywhere so I had to decline to cast it.
Ran into this issue too, so it hasn't been fixed. The card was even put into the live the dream cube, and it could easily impact my results...
