UR Aggro looks to race you with cheap blue and red threats while countering your key spells with Boomerang Basics and Flow State, so your priority is ensuring your early landfall triggers outpace their board presence. Surrak, Elusive Hunter provides a resilient threat that is difficult for their bounce-heavy gameplan to answer cleanly. Pawpatch Formation and Heritage Reclamation give you instant-speed interaction to protect your board and punish their tempo plays. We cut the sorcery-speed Planar Engineering and the slower Keen-Eyed Curator since the game is typically decided before they become impactful, and trim Meltstrider's Resolve as it underperforms when we need to be developing our board quickly.
Dimir Excruciator is a controlling midrange deck that pressures your hand with Duress and Bitter Triumph while setting up Doomsday Excruciator and Superior Spider-Man as threats that can invalidate your board state. Your landfall engine is resilient to spot removal, so prioritize keeping your creature density high and your land drops consistent. Surrak, Elusive Hunter comes in as a threat that generates value while being difficult to answer cleanly, and the Origin of Metalbending lessons give you flexible interaction against their discard-heavy gameplan. Trim the singleton Planar Engineering and some copies of Meltstrider's Resolve since their value diminishes against a deck packing heavy hand disruption that can strip them before you use them. Heritage Reclamation hedges against their graveyard-based threats like Doomsday Excruciator recurring or generating value from the bin.
Jeskai Control aims to answer your threats one-for-one with No More Lies, Lightning Helix, and Get Lost while burying you in card advantage through Stock Up and Consult the Star Charts. Surrak, Elusive Hunter provides a threat that is difficult to interact with cleanly, putting pressure on their counterspell mana. Origin of Metalbending and Pawpatch Formation give you instant-speed plays to pressure their end step and punish tapped-out turns, keeping you threat-dense through their sweepers. Trim Planar Engineering and Keen-Eyed Curator, as expensive sorcery-speed spells are too slow and easy to counter, and Meltstrider's Resolve underperforms when they're not attacking you.
