Quick Reactions triggered, but remained large size when returning to my hand, blocking me from clicking on the newly drawn card to use it. Clicking on the enlarged card in any way failed to restore it to normal. Fortunately when I drew more cards next turn it did collapse.
Gladiatorial Arena, Final. Opponent played arc lightning on me. I succeeded with Duck and recieved arc lightning. I played arc lightning on opponent. Holloborn the Nimble used quick reactions. When it went back into his hand it was giant. I played Deadly Spark and he used quick reaction again which made it go back to normal size.
