when a card is transmuted into an energy, it is turned upside, whether in the hand or on the field.

so say for example, the other player used Information's effect on you, and you had Grug (creature/entity) in your hand, and they transmuted it into a land.

Then, during your turn, you could play the now converted Grug as an energy, and gain access to his Energy effect. these are written upside down because they only become available when the card is played as an energy/land.

Grug's energy effect basically allows you swap an entity(creature) or structure(artifact/wall) in your hand with an entity (creature) or structure (artifact/wall) in the archive (discard)
