At its core, this is a 2/4 Elf Druid that acts as a consistent toolbox for creature-heavy decks
It's not as synergetic and strong as you'd want, as opposed to the best deck from this set at #1
Some aggro decks want to go wide, flooding the board with small creatures and finishing with a pump spell or anthem effect
For example, in the same deck you can include four copies of Stitch - Carefree Surfer and four copies of Stitch Rock Star
Most interestingly, the activated ability on Hauntwoods Shrieker allows you to flip face-down cards up for free, even your opponents' if you want to maybe because its a bad card, or to make them lose the flip-up trigger timing
In tandem, they motivate your opponents to go after one another, allowing them to cast more spells, which you in turn draw cards from
