Not only did it copy Symphony of Sins, which based on all other copy cards (School teacher, the priest ones, etc) it shouldn’t be able to. It was in fact, in my deck, and yet it still was copied.
Was the spell in your deck or in your hand when it was copied, or had it already been played? Hipster only looks at the deck as it exists the moment Hipster is played.
I don’t understand your reference to “school teacher, the priest ones, etc”
The card WAS in my deck. It copied it anyway. The reference to school teacher/etc is that those aren’t able to copy legendary spells, for obvious reasons.
Only rogue and dk legendary spells can’t be discovered. Others are allowed.
