The idea is to play Scarlet Webweaver into (the automatically corrupted version of) Fleethoof Pearltusk as early as possible for nice swingy turns. The rest of the deck is more on the reactive side, with cards like Desert Spear, Diving Gryphon (which also tutors your Pearltusk) and Overwhelm (which combines great with the rest of the deck). Polkelt draws you straight up into your combo. Shan’do can give all of your beasts +1/+1 in beforehand, or can copy one of your big rushers.
Nice idea.
