There's just enough RANGED minions to make this deck. It's naturally low to the ground, on curve and projectiles play well with lethal damage. I also always wanted to put Bailey in a deck - and it's so thematic to put a Bailey on a Vantage Hills and start pinging away! Telekinesis is a tech play to get back stolen Daggers which your opponent will undoubtably try to steal. The Thunderstorm is there to play in the opponents backrow to encourage them to advance their minions into the archers' range. Blink and Whirlwind are for positioning. Rain of Arrows is flavor and token removal. Also Tempest + Ranger is a common RPG theme. Sites provide defense, a bit of a maze to force enemy minions through kill zones.
