Bond Monsters are monsters that have the Bond line in the type text. They only exist for Extra Deck Monsters. For the Summon, you can use up to 1 (and only 1) monster your opponent controls that would be an appropriate material for that Summon, and Summon that monster. However, if you used an opponent's monster for that Summon, it cannot attack or activate its effects this turn. So, for instance, a Spellcaster/Fusion/Bond/Effect can be Fusion Summoned like any ordinary Fusion Monster, but you can only use 1 opponent's monster that would be an appropriate material for that Summon. Same for Synchro, Xyz, or anything Extra Deck-related. But if you use that opponent's monster, your Bond Monster cannot attack or activate its effects that turn.
