Sorcery
Planar Chaos
70/100
Gains value in 2HG: extra turn.
Teammates share one turn, so an extra turn is an extra turn for both players — double the value of the same card in a duel.
Ratings start at a neutral 50 and are adjusted by rules derived from 2HG's structure — shared 60 life, shared turns, two opponents. They'll be recalibrated against real play rates once teams start submitting decklists.
When you cast this spell, any player may pay half their life, rounded up. If a player does, counter Temporal Extortion. Take an extra turn after this one.
