In what circumstances can players draw additional cards during their turn?

Players can draw additional cards during their turn when a card effect specifically allows them to do so. This refers to instances where a spell or ability explicitly states that the player may draw cards, such as in the case of certain effects that trigger when certain conditions are met or when specific cards are played.

For example, a card might say, "Whenever you gain life, draw a card." In such cases, the effect grants the player permission to draw cards beyond the normal card-drawing rules at the beginning of their turn. These triggered or activated abilities allow for flexibility in the game and often enable players to build strategies that take advantage of drawing extra cards.

In contrast, exceeding a hand limit does not provide a player with an opportunity to draw cards; instead, it requires them to discard down to that limit. The phases of the game do not inherently grant extra card draws unless specified by a card effect, and drawing cards is not limited to attacking an opponent; combat does not influence drawing cards outside of specific card effects. Thus, the only scenario that guarantees drawing additional cards is through specific card abilities.
