At the beginning of combat on your turn, you may attach any number of Equipment you control to target creature you control.
Beatrix is a mono-white Equipment Voltron/aggro commander that lets you reattach any number of Equipment for free at the start of combat each turn, dodging equip costs entirely. You ramp into Equipment and creatures, then load up a hexproof or evasive carrier (or Beatrix herself with vigilance) to crash in for lethal commander or combat damage. Each turn you can shuffle your gear onto the best attacker, keeping equip-heavy boards mobile and threatening.
Free reattachment sidesteps the format's biggest Equipment tax—equip costs—letting you wield expensive gear cheaply
Vigilance means she swings and still stays back to block, great as a Voltron carrier herself
Mono-white has deep access to Equipment tutors, anthem effects, and protection
Flexible turn-by-turn: move all your gear onto whichever creature is unblocked or protected
Trigger only fires on your combat, so it does nothing defensively or at instant speed
Heavy reliance on a single carrier makes you vulnerable to spot removal and board wipes
Mono-white lacks card draw and ramp compared to other colors, leading to grindy hands
If Beatrix or your gear-stacked creature is answered, you lose tempo and value fast
Equipment-matters decks are slow to set up and weak to artifact destruction
