I also really enjoy how synergistic this version of the Doctor is with Amy Pond and her partner, Rory Williams
The key is how many artifacts, sagas, and legends you can get into a deck, because if you can untap it a few times, this card will win a game for you in short order
if you had a character with Rush you could keep swinging at an opponents character to earn lore, then replaying your character when banished before repeating
Often decks that were based on creatures in game one can spring this card on their unsuspecting opponents in game two and ride their direct damage to victory against a player who suddenly has no way to win
But its the second ability that really puts Sunforger on this list
Its not only impressive graveyard hate, but also a solid threat against a variety of decks
