I play a vadrok combo deck, and some turns can take awhile with many spells cast. Sometimes this creates a large stack that needs to resolve after I play or re-play show of confidence. The problem is, the game will sometimes force a draw when I still have time on my rope.
In this screenshot, all but one dragon was played in one turn. This was just the start of my second rope. I still probably had ~25 seconds to swing and end the turn. The game forced a draw in the middle of resolving the stack instead.

The only workaround I've found is just to limit my turns significantly, which isn't a problem most of the time once I get the combo rolling, but in some games with large board states on both sides it's an issue while I try to unsummon or kill the board state so I can swing.
