Cyclonic Rift has now bugged out for me twice, in two distinct ways:

• First time, it returned ALL permanents to players hands, including all of mine. There was no other effect on the field that would have made this happen, and no spell cast by the other player. The other player was completely tapped out.

• Second time, the game would not allow me to play Cyclonic rift at instant speed. I had all mana untapped, anticipating that my opponent would cast their commander (Minwu), and then attack with their tokens. I intended to Cyclonic Rift Winwu on the stack, once Minwu entered the battlefield. However, the game passed through to Blockers stage, and then when I chose no blockers, in order to then attempt to cast Cyclonic Rift on that stack, it passed through and allowed all the damage, then passed to my turn.
