Earthshape Always gotta pay attention to these new mass protection spells

An Aura put onto the battlefield this way doesn't target anything (so it could be attached to a permanent an opponent controls with hexproof, for example), but the Aura's enchant ability restricts what it can be attached to

Otherwise, determine which cards should be part of your investment strategy and hold until the next bull cycle

Unfortunately, there has been no indication that any cards no longer available will return to the game nor that they can be traded but for posteritys sake, heres every promo card in the Promo A series
