Theoretically Webspinner is pure card advantage. At the very least it replaces itself (gives you another 1/1 such as Captain's Parrot). Also it could potentially give you ANOTHER Webspinner for real shenanigans. Not saying it's a good card, but it is card advantage.
Great episode, as usual.
I wish Blizzard would adopt a consistent wording system like magic. This card should probably read "Deathrattle: Place a random beast card in your hand" or something. On other cards in HS, draw can mean from your deck etc.. That's the beauty of magic's system, once you learn their 'language', you will always know exactly what future cards do.
