Strategy[edit | edit source]

While Arcane Dynamo has very low stats for its cost and single-card Discover effect, its utility comes from the precision with which it can Discover powerful Spells. 5 Mana or greater-costing spells aren't as common as cheaper Spells, meaning for certain classes such as Shaman, you have much greater chances of Discovering a game-changing Spell such as The Storm Bringer. Overall Hunter, Rogue, Shaman, Warlock and Warrior tend to have the fewest expensive Spells, making Arcane Dynamo more reliable with those classes; while it can still be used in Druid, Mage, Paladin and Priest decks, there are greater odds that specific cards you're hoping to Discover won't be among your three options.

Being an Even-costing card, Arcane Dynamo can be used in decks centered around Genn Greymane to obtain odd-costing Spells such as Brawl or Luna's Pocket Galaxy that you'd normally be incapable of including in your deck.
