Mettalia is all colors.
Mettalia has protection from each color among cards she's salvaged in exile.
When Mettalia enters, for each color, you may salvage a nonlegendary card of that color. (Exile one from your graveyard until this creature leaves the battlefield. Whenever this creature deals combat damage to a player, put a card it salvaged into your hand.)

As an additional cost to cast this spell, discard a card.
Search your library for a card with mana value X or less, where X is 1 plus the discarded card's mana value, reveal it, put it into your hand, then shuffle.
