The Echo Flower was added in Beta 3.0.
When placed, it will copy a random opponent's card in their hand and put the clone into your hand, with a 1G cost drop. This will also copy any of the additional stats added onto it such as increased hp or attack, cheaper cost etc., but will instead copy over the original version to your hand. Copied cards can include Generated cards. It can clone spells of your opponent's class without problems.
