The discovered minions will be eligible for effects that buff minions in your hand (like Scourfin, for example).

Therefore only pick it if you are rather familiar with the current minion pool (https://bgknowhow.com/bgstrategy/?show=minions) and are able to make good decisions based on this knowledge.
