So... Did the actual math on Travis Woo's new combo list (the one with yew spirit and 4 bell ringers) assuming that somehow you cast primal surge using 10 lands and all other permenants are in library or untapped, you can get 202 mana. Activate Yew Spirit 50 times. You now have: 1 3.3777e15/3.3777e15 Yew Spirit 4 5/5 Craterhoofs 4 5/5 Arbor Elves 4 5/5 Archdruids 4 1/1 Pilgrims 4 1/1 Scorned Villagers 4 1/4 Bell-Ringers 1 1/1 Wild Beastmaster (enchanted w/ reflection) Now, let reflection trigger resolve. you now have: 1 3.3777e15/3.3777e15 Wild Beastmaster 24 1/1 Wild Beastmasters 1 1/1 Wild Beastmaster (enchanted w/ reflection) You let 4 craterhoof triggers resolve (reflection trigger still on stack) you now have: 1 3.3777e15/3.3777e15 Wild Beastmaster 24 105/105 Wild Beastmasters 1 105/105 Wild Beastmaster (enchanted w/ reflection) When you attack, each wild beastmaster triggers, putting the big one on stack last. it give all others +3.3777e15/3.3777e15, the next gives +3.3777e15/3.3777e15, the next gives +6.7554e15/6.7554e15, etc... you end up with: 1.1334E+23/1.1334E+23 Wild Beastmaster 1.1334E+23/1.1334E+23 Wild Beastmaster 1.1334E+23/1.1334E+23 Wild Beastmaster 1.1334E+23/1.1334E+23 Wild Beastmaster 1.1334E+23/1.1334E+23 Wild Beastmaster 1.1334E+23/1.1334E+23 Wild Beastmaster 1.1334E+23/1.1334E+23 Wild Beastmaster 1.1334E+23/1.1334E+23 Wild Beastmaster 1.1334E+23/1.1334E+23 Wild Beastmaster 1.1334E+23/1.1334E+23 Wild Beastmaster 1.1334E+23/1.1334E+23 Wild Beastmaster 1.1333E+23/1.1333E+23 Wild Beastmaster 1.1333E+23/1.1333E+23 Wild Beastmaster 1.1332E+23/1.1332E+23 Wild Beastmaster 1.1331E+23/1.1331E+23 Wild Beastmaster 1.1328E+23/1.1328E+23 Wild Beastmaster 1.1323E+23/1.1323E+23 Wild Beastmaster 1.1312E+23/1.1312E+23 Wild Beastmaster 1.1289E+23/1.1289E+23 Wild Beastmaster 1.1245E+23/1.1245E+23 Wild Beastmaster 1.1157E+23/1.1157E+23 Wild Beastmaster 1.0980E+23/1.0980E+23 Wild Beastmaster 1.0625E+23/1.0625E+23 Wild Beastmaster 9.9170E+22/9.9170E+22 Wild Beastmaster 8.5003E+22/8.5003E+22 Wild Beastmaster 5.6668E+22/5.6668E+22 Wild Beastmaster (enchanted w/ reflection) This is a total of: 2.8334e+024 damage.
