Well, one of my 8 decks -I´ve got a thousand and several hundred cards, so I can afford those luxuries- is a red-black earth-breaker, with only 7 creatures, but there are some "insignificant" threats to those who manage to slip some spells through: engineered Plague -useful against Elven decks with 3 lands-, a Millstone, a Well of Discovery, a Seismic Mage for dumping useless cards & extra lands, a Rhystic Tutor, two Barbed Wires for direct damage, some double-use cards like Pillage, Befoul & Co., and, in case things get out of hand or I´m swimming in mana, a Tectonic Break.
The decision of leaving the Tempest, Urza, and Mercadian Masques packs out of Extended has left only one deck of the 8 available to me, but, as I play in non-DCI-sanctioned tournaments where it´s a free-for-all, who cares? we Argentinians don´t care about such petty half-official rules.
And we play multiplayer (Emperor, Guerilla, etc.) so we don´t have to worry about much.
