If they dont, the premium versions of these cards will likely be a little less premium
You can wield spells (Sorceries and Instants) that allow you to destroy creatures, trigger various one-time effects, or most important of all, draw more cards
If you do, Leyline of Lightning deals 1 damage to target player or planeswalker
If it is surrounded by a golden ring then the card can instead be turned into ink in the inkwell
The most important thing is stabilizing, chewing through your opponents resources, and coming out on top
Another fairly similar idea is to take the same planeswalker and Spell Queller core and combine it with Urza instead of Mystic Sanctuary: Creatures (15) Planeswalkers (5) Lands (19) Spells (21) Here its very important that the Gilded Goose is Gilded Goose instead of Birds of Paradise or Noble Hierarch because the Food is being used to turn on Mox Opal and decrease the cost of Emry, Lurker of the Loch
