Changes

* There can be multiple chains in the [[Battle Step]] before entering the [[Damage Step]]. Only the initial chain can directly respond to the attack, and only in this [[Chain]] can you activate cards such as "[[Mirror Force]]", "[[Sakuretsu Armor]]", and "[[Magic Cylinder]]" (Cards that can only be activated when your opponent's Monster declares an attack). Cards that do not have this restriction ("[[Book of Moon]]", "[[Compulsory Evacuation Device]]", "[[Waboku]]", etc) can still be activated in another Chain before entering the Damage Step.<ref>[https://tcg.konami-europe.com/judgeforum/forum/viewtopic.php?f=6&t=227&sid=94fad95100f069b2562d467fc4a512ee Konami Judge Program Forum]: Chains / Cadenas</ref><ref>[https://tcg.konami-europe.com/judgeforum/forum/viewtopic.php?f=6&t=403&sid=3ba953a1baaa2df43fb7f36589b12e10 Konami Judge Program Forum]: battle phase timming</ref><ref>[https://tcg.konami-europe.com/judgeforum/forum/viewtopic.php?f=6&t=489&sid=a694a8cf00ac64360ab2f99dd581f6a2 Konami Judge Program Forum]: Attack response</ref>
