Whenever Kaalia attacks an opponent, you may put an Angel, Demon, or Dragon creature card from your hand onto the battlefield tapped and attacking that opponent.
Resolve Kaalia, protect her, and swing turn after turn to cheat huge Angels, Demons, and Dragons directly into combat tapped and attacking. Each attack snowballs board presence and damage while skipping the mana cost on your fattest threats. You close games fast with evasive beaters and devastating attack triggers.
Cheats enormous threats into play for free every combat, generating massive tempo and mana advantage
Built-in flying evasion lets Kaalia connect reliably to trigger her ability
Deep pool of bomb Angels, Demons, and Dragons with powerful attack/ETB triggers
Mardu colors give the best removal, board wipes, and recursion in the format
Heavily commander-dependent; without Kaalia the deck stalls with a hand of overcosted fatties
Vulnerable to removal, blockers, and fog effects on her attack step
Sorcery-speed payoff—Kaalia must survive a full turn cycle before triggering
Mana-hungry and clunky if Kaalia is repeatedly killed, raising commander tax
Hexproof angel that shields Kaalia and you from sacrifice and targeted effects.
Add fast mana and haste enablers (Lightning Greaves, Swiftfoot Boots, Sol Ring, Mana Crypt) so Kaalia attacks safely the turn she resolves. Prioritize bombs with immediate impact like Master of Cruelties, Rakdos, and extra-combat angels, and include reanimation (Reanimate, Animate Dead) to deploy fatties even when Kaalia is suppressed. Round out with premium removal and protection so a single board wipe or kill spell doesn't end your game.
