When Kassandra enters, search your graveyard, hand, and library for a card named The Spear of Leonidas, put it onto the battlefield, then shuffle.
Whenever a creature you control with a legendary Equipment attached to it deals combat damage to a player, draw a card.
Suit up Kassandra (or another creature) with The Spear of Leonidas and other legendary Equipment, swing in with haste, and draw a card every time an equipped creature connects to refuel your aggression. You're a midrange equipment-aggro deck that snowballs card advantage off combat damage, turning a single legendary Equipment into a card-draw engine.
Free, guaranteed Equipment on ETB via The Spear of Leonidas tutor—your engine is always online
Built-in card advantage that scales with multiple equipped attackers
Haste lets Kassandra pressure immediately and refill on the turn she lands
RW gives access to cheap, efficient equipment, anthem, and extra-combat effects
Heavily commander/equipment-dependent—removal or recurring bounce on Kassandra slows you badly
Card draw only triggers on legendary Equipment, narrowing your gear choices
No interaction or ramp baked in; RW lacks strong card advantage and recursion outside combat
Vulnerable to board wipes and creature-based blockers that stall your attackers
Free equip costs and card draw on artifact ETBs supercharge an equipment-centric build.
Lean into cheap legendary Equipment (the Mirran swords, Embercleave, Kaldra Compleat) plus free-equip enablers like Puresteel Paladin and Sigarda's Aid to maximize triggers. Add protection and evasion—Swiftfoot Boots, Whispersilk Cloak—so Kassandra survives and connects, and include extra-combat effects like Aggravated Assault to double your draw and damage. Round out with efficient ramp and a few targeted removal/board-wipe answers since RW struggles with resilience.
