11 Scar, Mastermind A shining, new era is tiptoeing nearer with this card
But because of how Arabian Nights was printed, some common and uncommon cards had fewer printings than others (there were no true rare cards in the set either, that wouldnt come until Legends released a year later.) The Mountain was one of the harder-to-find cards in the set, leading to a relatively small number of copies available to players
Drawing one card a turn seems fine except Narset, Parter of Veils is not symmetrical
That argument bears fruit (or treats, or kibble, etc.) when you look at the most valuable Dog cards versus the most valuable Cat cards

Of course, Im enough of a maniac to play Cascade Wurm, Bituminous Blast, and Bloodbraid Elf in the same deck: "Crazy Cascading Ketita" Creatures (14) 2 Enlisted Wurm 4 Baneslayer Angel 4 Bloodbraid Elf 4 Sprouting Thrinax Planeswalkers (2) 2 Ajani Vengeant Spells (18) 2 Path to Exile 3 Bituminous Blast 3 Lightning Bolt 3 Day of Judgment 3 Maelstrom Pulse 4 Captured Sunlight Lands (26) 1 Plains 2 Forest 2 Mountain 2 Swamp 2 Marsh Flats 2 Sunpetal Grove 2 Verdant Catacombs 3 Arid Mesa 3 Rupture Spire 3 Savage Lands 4 Jungle Shrine Captured Sunlight, for instance), but this is what came up when I Googled Four-Color Cascade Control. In a time when Jund was the only real deck, I saw a similar list in the Magic Online dailies and declared, Im playing that at FNM. This was probably among the most fun decks Ive ever played, mostly because all your cascades were insane
