This combo deck lives and dies by Blade of the Bloodchief and Basking Broodscale, both mana value 1-2, making Abrupt Decay premium interaction that cannot be countered and kills either piece or Urza's Saga before it ticks to chapter III. Outland Liberator can sacrifice itself to destroy Blade of the Bloodchief or Urza's Saga directly, giving us a second line of attack on their key artifact. Kraul Harpooner adds another cheap body that can fight and pressure while we dig for our own combo pieces with Green Sun's Zenith and Nature's Rhythm. We cut the top-end and situational cards that are too slow to matter before they assemble their loop.
