Or have you been in a heated debate before buying a card and doubting its legitimacy for a second
Its Solemn Simulacrums car, so to speak
Im not sure that this deck really needs three Game Changers to fall into the Upgraded Bracket (3), but it does tend to run out of cards sometimes, so Im adding Ad Nauseam and The One Ring to help shore up that weakness
4 Inzerva, Master of Insights (Heroes of the Realm) - A 3 mana dragon planeswalker, with a +2 that draws 2 and discards 2, a -2 that fateseals 2 and scrys 2, and - most notably - a -4 that makes it so that whenever an opponent draws a card, they take 1 damage, and also makes them play with their hand revealed
Thanks to this, the card sees a decent amount of play in Legacy and Premodern
Do that and you will know in minutes whether your old binder holds a few dollars or a genuine grail
