Yu-Gi-Oh: 10 Most Powerful HERO Cards
8. Elemental HERO Shadow Mist
When Shadow Mist debuted in the HERO Strike Structure Deck, it redefined the archetype's place in the meta forever, such is the power of her twin abilities.
The first has seen its use dwindle, but is no less potent; a free Mask Change or variant when special summoned. A trumphant effect when used in combination with Liquid Soldier, Solid Soldier, or with Foolish Burial and Monster Reborn, playing Shadow Mist effectively can put a Masked HERO on your board immediately, usually the much feared Dark Law. This was and is especially valued due to the lack of ways to search Change cards from the deck.
Her second ability lets you search any other HERO from your deck to hand when she's sent to the GY. While the two effects can't be triggered on the same turn, this on makes Shadow Mist ideal discard fodder since you can immediately replenish your hand with another HERO, one who may have a better use at crucial points.
