A two-mana, 2/3 minion seems an unlikely card to build a deck around, but that's what happened with Even Shaman.

Murkspark Eel, the card in question, has a useful battlecry that can eliminate an enemy minion. And it turns out that using even-only cards lets you build a very effective version of the basic "minion shaman" beloved of many new players. Here's how it works.

Deck code:

The new Boomsay version of this deck is cheap compared to earlier builds. And even then, some of the big cards are not essential. The Lich King, for example, does well but is not a linchpins of the deck.

That leaves you with Genn as the only essential legendary. Which he is, because it's his power that makes the whole "even" shtick work.

As for replacements, if you want to run a more offensive game, start by doubling up on the single cards, in particular Knife Juggler.

You can also push the deck the other way, toward more defensive play, with cards like Plated Beetled and Defender of Argus. Finally, one copy of tech cards like Spellbreaker and Acidic Swamp Ooze can often come in handy.
