Legendary Creature â Elf Scout
Parley â€” : Each player reveals the top card of their library. For each nonland card revealed this way, add and you gain 1 life. Then each player draws a card.2/4
Selvalaâ€™s parley ability is a mana ability. It doesnâ€™t use the stack and canâ€™t be responded to.
If you activate Selvalaâ€™s ability while casting a spell, and you discover you canâ€™t produce enough mana to pay that spellâ€™s costs, the spell is reversed. The spell returns to whatever zone you were casting it from. You may reverse other mana abilities you activated while casting the spell, but Selvalaâ€™s ability canâ€™t be reversed. Whatever mana that ability produced will be in your mana pool and each player will have drawn a card.
Except in some very rare cases, the card each player draws will be the card revealed from the top of their library.
