Chandra's Flame Wave deals 2 damage to target player and each creature that player controls. Search your library and/or graveyard for a card named Chandra, Flame's Fury, reveal it, and put it into your hand. If you search your library this way, shuffle.
Chandra’s Flame Wave targets the player, not their creatures. A creature with hexproof may be dealt damage this way.
If the target player is an illegal target by the time Chandra’s Flame Wave resolves, the spell doesn’t resolve. No creatures or players are dealt damage, and you won’t search for Chandra, Flame’s Fury.
