The ability to pull cards out of the Discard Pile is incredibly important in Lorcana for two main reasons
I find I end up only playing it in decks that want a high artifact count and have good synergy with them as middle curve filler, quite a lot like Solemn Simulacrum
They were, however, a little weak to interaction and wraths, meaning the ones that didnt have a strong EtB or easy way to flip them (like Liliana and Nissa) hinged on you keeping them in play
And, as with any Magic set, that includes some beautiful tokens
Which means by the time we see a Blue Ugin judge foil, a set foil Ugin could be worth $120 $130 and even if a non-foil Blue Ugin were to be worth a mere $10 $20 more, Blue Ugins would probably still command a price range of $130 $150
