The card's an interesting one
You don't have to attack with the creature with dash unless another ability says you do
We currently have a Steel Beast Hardheaded from The First Chapter which offers a different style of play, however the new Emerald version opens up a much more aggressive approach
There are a couple of decent questers with high Willpower and high lore value in this deck, like Robin Hood, Daydreamer and Starkey, Devious Pirate, but more often than not you'll get more value out of steadily questing with an unanswered Don Karnage than you will with an intimidating late game bomb
This is fine if you stack your deck with lots of cheap characters or some of the Merlin characters (which you will greatly benefit from bouncing back to hand)
This maximises your chances of drawing a great card when you need it and can afford it, without it also sitting dead in your hand for a whole game
