Unless an effect allows you to play additional lands that turn, you can play land cards exiled with Harnfel only if you haven’t played a land yet that turn. In most cases, if you exile two land cards with Harnfel, you won’t be able to play both.

The cards exiled by Harnfel’s activated ability are exiled face up.

The mana value of a modal double-faced card is based on the characteristics of the face that’s being considered. On the stack and battlefield, consider whichever face is up. In all other zones, consider only the front face. This is different than how the mana value of a transforming double-faced card is determined.

You must still attack with a creature you control to activate its boast ability.

Playing the cards exiled with Harnfel follows the normal rules for playing those cards. You must pay their costs, if any, and you must follow all applicable timing rules. For example, if one of the cards is a creature card, you can cast that card by paying its mana cost only during your main phase while the stack is empty.

In the Commander variant, a double-faced card’s color identity is determined by the mana costs and mana symbols in the rules text of both faces combined. If either face has a color indicator or basic land type, those are also considered.
