This is the Pantry Spider HS Card released in the adventure mode One Night in Karazhan. It’s a neutral card, a beast, costs 3-mana, and has a 1/3 body.
The card reads: Battlecry: Summon a 1/1 Spider.
So, it’s a beast synergy card with a total of 2/4 stats for 3 mana. Nothing special here, it might be a good pick in arena as the extra body can benefit from buffs. As far as putting it in a Beast Hunter deck, or a Beast Druid deck, there are better 3-drops to choose.
