What I find interesting regarding the different executions in Outlaws of Thunder Junction alone is that we see cards that are cheaper to plot than to just cast from your hand, cards with the cost to plot as to cast normally, and cards that cost more mana to plot

Mostly youll just swat away a removal spell and make an opponent kill their own creature, but sometimes you redirect a Time Warp to yourself or completey rearrange what a Crackle with Power was targeting
Whenever you cast a noncreature spell, you choose one of the following options that hasn't already been chosen that turn: Solar Beam - The Vision gains Double Strike until the end of the turn Destiny Control - The Vision gains Indestructible Technopathy - Draw a card This is similar to how Monument to Endurance works, a popular artifact from Standard used most commonly in Izzet decks, only it activates with noncreature spells being cast and not discards
