They should usually be (much!) lower after release, but since many of these cards will be sought-after collectibles and some will likely be bought by FF collectors that have no interest in ever playing Magic there's no way to know the final price
When you take battle damage, while this card is in your GY: You can Set this card
The aim is to get as many monsters onto the field as early as possible in order to create a board that your opponent will find difficult to overcome
Master Duel decks that are exceptionally fast may overwhelm a Dark Magician deck before it gets started, and thats important to note
Urza blocks well, doesn't get hit with Cut Down or most Red removal, curves into a turn four The Mightstone and Weakstone, but most importantly cost reduces almost all of your spells
Although, Im afraid theres no digital release this time around (sorry, MTG: Arena fans)
