Whenever Liberty Prime attacks or blocks, sacrifice it unless you pay (two energy counters).
, , Sacrifice an artifact: You get and draw a card.
Liberty Prime is a 5-mana Jeskai energy engine on a body: keep it fed with energy so it can attack and block freely, and use its sacrifice-an-artifact ability to convert spare artifacts into energy and cards. You build an artifact-heavy battlefield, generate a steady stream of , and grind out value while swinging with a vigilant, trampling, hasty beater. Win by going wide/tall with artifacts, looping recursion fodder for cards and energy, or assembling an energy-fueled combo or big mana payoff.
Comes online immediately with haste, vigilance, and trample for relevant combat pressure
Built-in card advantage engine that turns spare artifacts into energy and cards
Energy is a flexible resource that synergizes with a deep pool of Kaladesh/Aetherdrift payoffs
Jeskai gives access to powerful artifact support, card draw, and removal
Sacrifice outlet pairs well with token artifacts, Treasures, and recursion loops
Self-sacrifices every combat unless you keep two energy banked, so an energy drought sidelines it
Needs a constant supply of artifacts to fuel its ability, making it artifact-dependent
Five mana and removal-prone—repeated recasting drains tempo
Energy synergies are narrow; without payoffs the can pile up unused
Wants both a wide artifact base and a deep energy package, straining deckbuilding space
Cheap artifact that banks energy and can itself be sacrificed for more, fueling the whole plan.
Tighten the energy package around true payoffs (Aetherworks Marvel, Aetherflux Reservoir, Decoction Module) and cheap fodder generators so Liberty Prime never goes hungry. Add fast mana and efficient artifact tutors like Whir of Invention or Inventors' Fair, plus protection such as Lightning Greaves to keep your commander on the board. Lean into a compact combo finish (energy storage into Marvel/Reservoir) to give the grindy engine a decisive closer.
