Ran into the exact same issue today. Cast Shiko, made token copy of Songcrafter Mage. Used Songcrafter Mage's ability on Dragonclaw Strike. I had 6 available mana (blue, green, and red), but the game passed through to combat without letting me cast Dragonclaw Strike. I could not cast it on my second main phase, either. This event directly led to a game loss in ranked Bo1 draft. Playing on Mac. Is there any possibility of a refund?
