{"ops":[{"insert":"CASS, HAND OF VENGEANCE — DECK PRIMER\nBoros Auras — Combo, Tokens, Ping. List inspired by Reminder Text (https://www.youtube.com/@ReminderText).\n100 cards: 60 spells, 40 lands. Nonland curve 0/1/2/3/4/5 mana = 1/18/18/17/3/3 cards, average 2.2.\nTHE COMMANDER\nCass, Hand of Vengeance ({2}{R}{W}, vigilance): Whenever Cass or another creature you control dies, if it was enchanted or equipped, return any number of Auras that were attached to it from your graveyard to the battlefield attached to target creature, then attach its Equipment to that creature.\nCass is a recycling plant. A creature dying while dressed re-clothes a new body for free, and Auras with enters-the-battlefield triggers fire again on every re-attach. Death is part of the plan: a board wipe just re-dresses your survivors instead of resetting you. She costs only 4, so recasting is realistic — she is the one card you protect.\n\nTHE COMBO\nPrimary loop (infinite ping): Cass + Mask of Immolation + one ETB-token Aura (Cartouche of Solidarity, Squire's Devotion, Nurturing Presence, Roadside Assistance) + one spare body.\n1. Sacrifice the dressed creature to the ability Mask grants: 1 damage to any target.\n2. It died enchanted and equipped, so Cass re-attaches the Aura and Mask to another creature; the Aura's ETB creates a fresh token.\n3. Repeat. Body count rises every cycle and each ping targets anything — kill the table.\nMortarpod replaces Mask. Grafted Wargear is a free outlet: Equip {0} moves it and sacrifices the old wearer, still triggering Cass.\nBody-printing variant: Cass + Archon of Sun's Grace or Ghostly Dancers + any sac outlet. Every re-attached Aura is an enchantment entering, so each sacrifice yields a 2/2 lifelink Pegasus or a 3/1 flying Spirit. Mask or Mortarpod then converts that army into damage.\nSwarm finisher: Murder Investigation on your biggest token — Soldiers equal to its power when it dies, plus re-attachment. Burn finisher: Pain for All (damage equal to the wearer's power on attach, reflected to each opponent). Combat finisher: Grim Reaper's Sprint — Morbid discount, +2/+2, haste, and an extra combat for the token army.\n\nTHE ENGINE\nDraw: Sram, Senior Edificer; Kor Spiritdancer (also +2/+2 per Aura); Mesa Enchantress; Pearl-Ear, Imperial Advisor (discounts enchantments, draws on modified targets); Armory Paladin; Tragic Poet (recycles an Aura). Seven ETB-draw Auras — Angelic Gift, Chosen by Heliod, Dragon Mantle, Feather of Flight, Rune of Speed, Pentarch Ward, Unquestioned Authority — draw a card again every time Cass re-attaches them.\nTutors: Heliod's Pilgrim (Aura), Moon-Blessed Cleric (enchantment), Open the Armory (Aura or Equipment — finds Mask), Axgard Armory (a land that tutors both late game).\nRamp: Sticky Fingers (Treasure on combat damage, card on death), Minimus Containment (removal that becomes Treasures), Roadside Reliquary.\n\nSUPPORT\nTokens: Archon of Sun's Grace, Ghostly Dancers, the ETB Auras above, Mandibular Kite and Glimmer Lens (living-weapon bodies), Momo, Playful Pet, Ornithopter.\nSac outlets: Betrothed of Fire (pump), Fanatical Devotion (regenerate — saves Cass), Martyr's Cause (damage prevention), Curious Farm Animals (destroy an artifact or enchantment).\nProtection: Swiftfoot Boots, Blacksmith's Skill, Shardmage's Rescue, Alseid of Life's Bounty, Pentarch Ward, Unquestioned Authority, Sheltered by Ghosts, Beloved Princess, Conqueror's Flail (opponents can't cast spells during your turn — combo-turn cover).\nRemoval: Darksteel Mutation (permanent ignore button), Minimus Containment, Grasp of Fate, Sheltered by Ghosts.\n\nGAME PLAN\nTurns 1-3: deploy a draw engine and cheap Auras; every card replaces itself or makes a body. Turns 4-6: cast Cass, dress one creature, start looping sacrifices for cards and tokens; tutor for Mask if missing. Combo turn: with Cass, Mask, and a token Aura live, start the ping loop behind Conqueror's Flail or Blacksmith's Skill, or swing under Grim Reaper's Sprint.\nMulligan: keep 2-3 lands with both colors plus a draw engine, or a cheap Aura and a body. Throw back all-engine/no-Aura and all-Aura/no-engine hands. Tutor priority: Mask of Immolation, then a token Aura, then an engine.\n\nWEAKNESSES\nCass is the engine — recast her at 4 and keep protection up. Graveyard hate blanks re-attachment; switch to normal casting and the token army. Enchantment removal strips the outfit piece by piece — spread Auras across two bodies. No counterspells: Conqueror's Flail and Blacksmith's Skill are the cover. Lifelink bodies offset life loss from aggressive lands.\nOptional upgrades: Ashnod's Altar, Impact Tremors, Purphoros, Sigil of the Empty Throne.\n\n"}]}
