A great example being Faerie Mastermind, who can draw you cards but also wear auras and equipment or trigger Coastal Piracy effects to draw even more cards
According to MTG's head designer Mark Rosewater, equipment was the highest-ranked mechanic in Mirrodin , and so flavorful and popular that Wizards of the Coast decided to make it evergreen
Closer to the $50 range, you have another set of Pikachu: the V and VMAX Ultra Rares, also from the Trainer Gallery
Its also under $40, making it pretty affordable for anyone looking to get started
But take the most expensive card in Magic, a Limited Edition Alpha Black Lotus
I don't think I have missed anything, certainly nothing that isn't greatly overshadowed by another card for that role in this breakdown but I am keen to hear if anyone thinks there is something worthy I have missed mentioning
