The funny thing about
Counterslivers is that for a long time champions of the deck on this forum, Volt and Pinder, poo pooed the inclusion of Aether Vial in that deck. They kept this attitude until Pinder actually tested the card in preparation for Grand Prix Columbus and came out and said that "Aether Vial is retardedly good". Since then a
new thread has been made but this time the opening post now lists Aether Vial under "automatic maindeck cards" as a 4 of.
Volt and Pinder arguing against the inclusion of Aether Vial in counterslivers stifled innovation for quite some by preventing the deck from reaching it's full potential. Loxodon Baileyarch has said himself that he hasn't played with vial in this deck but seems certain that it's no good so he dismisses outright instead of actually playing with it. This is an attitude that will only serve to stifle innovation.
