Change the algorithm of suggested price to also include cards from similar rarities.

Some of the collections have very high priced cards that don't get sold very often due to their value. It would be nice if AH was able to add a condition to search for similar cards in the collection with like rarities when there is little to no sales data on that particular template.

For example in kogs if a kog is foil and set s2 compare it to the price of other s2 foils. Or warsaken if a card is rank 4 and gold compare it to the average sale of all rank 4 gold cards.
