Define "Transform."

"Transform" refers specifically to the mechanic in Magic: The Gathering involving double-faced cards, which have two different sides. The process of transforming a card involves turning it over so that its other face is facing up, representing a change in its characteristics or state. This mechanic is commonly seen in cards that have different forms or abilities depending on certain game conditions.

The transformation mechanic is key to gameplay involving double-faced cards, as it allows for dynamic shifts in how a card can be played and interacted with. It's not simply about changing the card's type or its identity; it specifically involves the physical act of flipping the card to reveal its other side, which is integral to the rules surrounding double-faced cards.

Other choices do not accurately reflect the definition of "transform" within the context of the game rules. The concepts of drawing a card or rearranging cards in hand are unrelated to the transformation of double-faced cards, and changing a permanent into a creature does not capture the specific action of flipping a card to display its other face. Thus, the definition provided in the correct choice is precise and aligns perfectly with how the transform mechanic operates in gameplay.
