Forum:Bottomless vs Imperial Iron Wall

This is about the ruling that states that Bottomless Trap Hole cannot be activated while Imperial Iron Wall is active. I don't understand why this is the case, because according to PSCT "In 'Do A, and if you do, do B', both A and B happen simultaneously. A is required for B, but NOT vice-versa." So even if you can't do B "banish" you should still be able to use BTH for A right? I'm wondering because I believe that BTH was changed from an "and" effect to an "if you do effect" after the ruling about its interaction with wall (probably wrong :p).Thechosenone124 (talk • contribs) 09:46, February 4, 2016 (UTC)
