This is 100 percent a matter of personal opinion, but to me, theres no sense in acquiring anything other than the least expensive version of a card to play with (within reasonIll pay a little more for an old-bordered version of a card, for example)
Cards like Ragavan, Nimble Pilferer pose a significant threat, Lightning Bolt stands out as an efficient removal spell, and Preordain is considered one of the best cantrips ever printed
As an example, thanks to The One Ring and the other serialized cards, we know exactly how many Collector Booster packs they printed of both the Holiday Edition and the summer edition
Sometimes, it was the wrong cost, as with Orcish Artillery, or lacking a casting cost altogether, such is the case with the original printing of Cyclopean Tomb
And, if you pair him with Bodyguard characters or cards that give him Ward, he can stay on the field for a while to come
