Primarily what this list is going to focus on is new cards, since there is only the one set that downshifted cards
Essentially, a deck that can get multiple lands out per turn, cast giant creatures early, and mash opponents to death using those giant creatures along with some trample sprinkled in here and there
Expand your collection with exciting new artifacts, creatures, and spells from the Kaladesh set
Chivalric Alliance and Glimmer Lens should be making their way into most white decks, and offer both card draw and token synergies
An effect like that isn't always what you want in an aggro deck, but knowing your options is a good starting point
Also, dont just look for comic book shows or big COMICON conventions as your only choice
