At that moment, I control Experimental Frenzy and Thermo-Alchemist and some other creatures, I can see the top of my deck is Light up the stage, My opponent controls the white god's sword, the white god's shield and the withe god, the white god's sword is equipped by soul warden, and a Rune of Sustenance is also attached to the soul warden.
I choose to tap my Thermo-Alchemist to deal 1 damage to my opponent, but before I can pay the Spectacle cost of Light up the stage to cast it(I still have 2 untapped mountain). The game skipped my turn.
The attached picture shows the next turn of mine. the two angles are put into the battlefield after all this happened.
Why the game skipped my turn and I can't cast Light up the stage by its spectacle cost?(I just deal 1 damage to my opponent by Thermo-Alchemist)
I think it's a bug.
