What first turn kill in multiplayer FFA provides the best ratios?
False Cure deck - I used to have a Vintage version of this deck, using proxies for all the expensive cards in the deck.


Play Overgrown Tomb ($14)
Cast 1xDark Ritual ($1)
Cast 1xFalse Cure ($1.50)
Cast 4xSkyshroud Cutter ($0.10) for alternate casting cost.


First Skyshoud Cutter causes opponents gain 5 life (25 life), False Cures and opponents lose 10 life. Remaining 3 Skyshroud Cutter's do the same.


7 Cards (AVG 22.9 life/card). Cheating a little since we are giving opponents life
6 Mana (AVG 55.3 life/mana), or using CMC instead 8.42
40 * 4 life = 160 total
$14 + $1 + $1.50 + 4x$0.10 (approximate $16.90 total, AVG 9.47 life/$) (Prices by TCGPlayer.com, 5th lowest Near Mint price)
