Jeskai Control wants to tax, counter, or bounce our spells (Spell Pierce, It'll Quench Ya!, Divide by Zero) and stabilize with Jeskai Revelation and Thor, God of Thunder, so proactive interaction beats combat tricks. Precise Redaction is narrow here, since most of their deck is not white or black, but Jeskai Revelation is white, so it can counter their biggest payoff spell. Rending Volley can't be countered and deals 4 damage to a white or blue creature, which makes it a clean answer to the blue Gran-Gran. Thor is red, so Volley can't hit it. Aether Gust hits red spells and permanents, so it can take care of Thor, God of Thunder or a Tablet of Discovery. It puts the target on the top or bottom of its owner's library, their choice, rather than returning it to hand, so it is tempo rather than card advantage. Cut Monstrous Rage and Boomerang Basics since their tax and bounce effects (Spell Pierce, It'll Quench Ya!, Divide by Zero) punish low-impact spells, and we want higher-value plays instead.
