The best part of some of these is that they have basic land types, even on dual and triple mana-producing cards
On the third turn, you could play 6 Elves, but instead you are probably attacking with some
Additionally, a new powerful card, Deputy of Detention has found its way into many versions of the deck, which allows it to make another tempo play, setting your opponent back, while allowing your attackers to strike unhindered
Crashing Footfalls has seen more play over the last few months, but I think people interested in Cascade decks may want to look closer at Living End for this tournament
Other ideas that were too pricey for the deck include Defense of the Heart, Dust Bowl, Strip Mine, Pernicious Deed, Oblivion Stone, Expedition Map, Mirrorpool, Traverse the Ulvenwald, Attrition, and maybe Primeval Bounty
