This spell selects a random minion in your hand and summons it to the field without activating it's Battlecry, while keeping any hand-buffs. Thus, this card is most useful on minions with passive effects or large stats. In particular, the Malygos Shaman deck appreciates the ability to have multiple Malygoss on the field, leading to absurdly powerful Lightning Bolts, Lightning Storms, and Lava Bursts. When combined with Electra Stormsurge, this card summons 2 minions to the field, leading to a whooping +10 spell damage for a total of 9 mana. If one is playing a less spell-heavy deck, this card can be used to summon an Earth Elemental without needing to worry about Overload, Al'Akir the Windlord who can charge to attack immediately upon being summoned, Walking Fountain for removal and healing, and Big Bad Archmage to generate a big board.

In Wild format, one can use the same Eureka-Electra combo to summon 2 copies of Ragnaros the Firelord, which will fire 2 8-damage fireballs at random enemy targets at the end of your turn, potentially getting rid of half of the enemy's total health. Overall, this is a very versatile card that can reliably boost any Shaman deck with strong minions that do not rely on battlecries.
