The difference between monsters and cards is like the difference between apples and fruit(all monsters are cards but not all cards are monsters), monsters apllies only to the cards called to the center, right and left, (e.g. monsters and impact monsters) monsters with transform, ride or station abilities are monsters unless you activate those abilities and equip the monster, in which case it will not be treated as a monster but as an item (e.g. abilities and costs that target/effect monsters won’t work on the equipped monster while abilities and costs that target/effect items will work on the equipped monster) however cards is considered all categories(e.g. monster/impact monsters/spells/impacts/items) soul is also considered to be a card, however a card in the soul of a monster on the field is not considered on the field( e.g. if you had a monster on the field with a card in its soul, your opponent’s card effect destroys a card on the field, the effect cannot chose the card in the monster’s soul as that card is not on the field)
