I am just saying this, but I officially hate this card.
Earlier today, I was playing in the arena. I play a control deck, but this time, I found MYSELF being controlled. My opponent, was playing Shard of Focus, which by itself would have been fine. But they played three of them almost immediately. In addition to that, they played Earthquakes, and Devourers. They played no permanents other than Quantum Pillars. I found myself facing down three Black Dragons, with no field, no quanta, and a hand full of cards that I couldn't play. This was literally THE most infuriating game I have played thus far. Even more aggrivating than the time, there was a desync error, and my opponent fully healed every turn. (Which I still won.)
