Most monsters have a "you can" clause so the effect isn't compulsory and BTH is still legal. There are a few cards that do it innately like Drill Warrior, Battle Searchers, Gorz. You can also summon something during the Damage Step where BTH can't be triggered xD To make BTH miss its activation you have to make an action without speed spell (those that don't start a Chain Link) happen right after the summon, you can't "chain" cards after the action since the opposing player has priority, note the action has to happen AFTER the monster is summoned, it can't happen at the same time. I'll take a look at it and try to fix, I'll see if I can do something about the BTH blunder too xD ROFLMAO, that's the second time someone points out a fail in there.
