Izzet Lessons is a tempo-control deck that aims to answer your threats with Abandon Attachments and Combustion Technique while accumulating card advantage through Artist's Talent and the Firebending Lesson package. Spider-Sense comes in to protect your key permanents from their removal suite and to punish their reactive game plan by forcing them to spend mana on your terms. Chandra, Spark Hunter provides a resilient threat that pressures their life total and is difficult to answer cleanly with their primarily instant-speed interaction. Gene Pollinator is a slower, more fragile payoff that gets outclassed in a removal-heavy matchup, and Improvised Arsenal is too low-impact when they can answer it efficiently. Your primary game plan is to deploy your cheap artifact creatures backed by Springleaf Drum to flood the board faster than their removal can keep up, then leverage Krang, Master Mind and Pinnacle Emissary as hard-to-answer win conditions.
Jeskai Control aims to answer your threats one-for-one with Get Lost, Lightning Helix, and counterspells like No More Lies before closing with Ultima or Wan Shi Tong. Your gameplan is to flood the board with cheap, resilient threats faster than they can answer them, leveraging Cavern of Souls to make your key creatures uncounterable. Chandra, Spark Hunter comes in as a threat that demands an immediate answer and generates ongoing value they must respect, while Spider-Sense protects your key creatures from Get Lost and No More Lies at instant speed. Improvised Arsenal and Synthesizer Labship are cut as slower, more situational cards that give the control player time to set up their countermagic mana. Keep your curve low and don't overcommit to the board when they have open mana — sequence your threats to force multiple answers and let Cavern of Souls do the heavy lifting against their counterspell suite.
UR Aggro threatens to kill you before your artifact synergies fully come online, so the priority is adding direct interaction and stabilization tools. Chainsaw gives you cheap, efficient removal to answer their early threats and keep the board clear for your robots to attack. Chandra, Spark Hunter provides repeatable damage removal while advancing your board, making it hard for them to stick key attackers. Improvised Arsenal and Chrome Dome are cut as lower-tempo plays that don't affect the board immediately — in a race you want every mana to matter. One copy of Synthesizer Labship also comes out to trim the top end; your core engine of Krang, Memory Guardian, and Ravenous Robots is enough to close out the game if you survive the early turns.
