There's nothing else here to sink my teeth into - no path, no buildings, no creatures, no weather, nothing to hold my interest beyond the prettiness of the art and scene
As for the latter, it digs you into your deck for a free creature each turn, so hand size isnt an issue
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
At three mana, Talion would be a completely different discussion
Im not sure a card like this has what it takes outside of Standard, but there are enough four-drops and greater for it to be a powerful threat there
