Hearthpwn

An extremely low-cost Token Druid list, this time for Standard. Gibberling blowouts are nice, but by no means required to win with this - excellent for climbing at low to moderate ranks (i.e. up to about Platinum) or farming gold.

General Use

Make tokens. Buff tokens. Go face. Trade exclusively when it's efficient.

Mulligan

The mulligan for this deck is slightly more complicated than one would expect, and is the main nuance when playing it.

When going first, your ability to have a blowout turn is greatly reduced. Generally, you'll want to get one of the sticky 1-drops (Ashtongue, Initiate, Treenforcements, even Beaming Sidekick in a pinch) into another combination of cards that fills your curve (a 2-drop or any pairing of 1-drops).

When going second, by contrast, blowouts are your primary objective. Mulligan away most cards that cost more than 1 (exceptions are Power of the Wild if you feel like you can stick it and Voracious Reader), and focus on having a robust turn one. This is where Gibberling really shines - even a coin into Treenforcements is an excellent start, and Nature Studies can chain into any other 1-cost spell for a bonus Gibberling.

Claw, but no Lightning Bloom?

In my experimentation with this list, Lightning Bloom underperformed - it's absolutely vital that every card you draw helps you stay on board or capitalize on board, and Lightning Bloom doesn't do this. More often than not, drawing it in the opening hand when going first caused me to lose the game. Claw offers a much more versatile position - it still functions with Gibberling, permits you to remove early threats to your board, and can serve as burn in a pinch. If you don't like this include, consider another sticky 1-drop like a Hot Air Balloon.
