Since Zirda, the Dawnwaker only cares about permanents, it could show up in a deck that is mostly (or exclusively) spells (people have mentioned this as a possibility in Vintage, where some decks incidentally meet Zirda, the Dawnwaker's restriction, although whether or not getting a random 3/3 in hand to start the game is worth a sideboard slot remains to be seen)
The +1 turns things into Elks
A few Double Exposure texture foil Legendaries like Kaito , Tyvar , and Niko were valued from $60 to $70, except Valgavoth
Informed Inkwright So long as the spells youre casting target creatures, Informed Inkwright will play out like a buffed-up Young Pyromancer, with better baseline stats and better token creation
That creature doesn't leave or enter the battlefield
The obvious choices for this style deck is any artifact that costs zero mana, like Lotus Petal, Mishras Bauble, and Lions Eye Diamond
