While a number of the cards from this set have aged poorly (looking at you, Skyshroud Behemoth), a number were notable threats at that time but dont quite make the cut on this modern value-based list: Lin Sivvi, Defiant Hero was the engine for Rebel decks from this era, Saproling Burst slotted perfectly into Fires of Yavimaya decks (and also formed an instant-win combo with Pandemonium), and Rising Waters fueled a brutal control deck alongside the various Stax pieces and counterspells from sets of this era
They are often heavily related, but a high price does not always guarantee a high value and vice versa
It also works well in the 99 of commanders like Kalamax, the Stormsire and Niv-Mizzet, Parun, that focus on spells
Despite being pretty cool and unique, Guff doesnt make the superfriends Commander strategy any more or less reliable than it was before
Instant and sorcery spells you cast cost one less generic mana to cast
