UR Aggro pressures with Slickshot Show-Off and Elusive Otter growing off cheap cantrips, backed by Burst Lightning for reach, so Elspeth, Storm Slayer's 0 ability puts a +1/+1 counter on your team and grants temporary flying, helping you block or race their evasive threats while her −3 removes a resolved threat with mana value 3 or greater. Ghost Vacuum is a cheap artifact that can exile instants and sorceries from their graveyard, undercutting Flow State and the cost reduction on Eddymurk Crab. Liliana the Faultless and Enlightened Confidant are both fragile 1-toughness creatures that die for free to Burst Lightning, trading down against a deck that wants cheap removal targets. Stabilize behind lifegain triggers to survive the early tempo onslaught.
