Text:

：怪物化３を行う。（このクリーチャーが怪物的でない場合、これの上に＋１/＋１カウンターを３個置く。これは怪物的になる。）
燃えさし呑みが怪物的になったとき、各プレイヤーはそれぞれ土地を３つ生け贄に捧げる。

Rulings:

• 9/15/2013 When the last ability resolves, the active player will choose three lands they control, then each other player in turn order will do the same. Then all of those lands are sacrificed at the same time.
• 9/15/2013 Once a creature becomes monstrous, it can’t become monstrous again. If the creature is already monstrous when the monstrosity ability resolves, nothing happens.
• 9/15/2013 Monstrous isn’t an ability that a creature has. It’s just something true about that creature. If the creature stops being a creature or loses its abilities, it will continue to be monstrous.
• 9/15/2013 An ability that triggers when a creature becomes monstrous won’t trigger if that creature isn’t on the battlefield when its monstrosity ability resolves.
