Jade druid is ove ... ResidentSleeper
And the reward is:
This card can be really good if you have the right legendary but it relies on RNG.So i think its not that OP.The original character/card comes from Pokemon.
Some explanations: This card can get any text no matter what.Like taunt,divine shield,lifesteal.It can evet get some better texts like Rotface's,Moorabi's and Ysera's texts.If the player selects a Legendary minion with a battlecry, it will get its text but it wont Trigger.Also mention that this card can not discover wild Legendaries if played on standard mode.
