You may have Sakashima enter as a copy of another creature you control, except it has Sakashima's other abilities.
The "legend rule" doesn't apply to permanents you control.
Partner (You can have two commanders if both have partner.)
Sakashima enters as a copy of your best creature while letting you ignore the legend rule, so you double up on powerful legendary creatures and ETB engines. As a Partner commander she's almost always paired with a stronger partner that defines the deck, while she provides a backup clone and protection from the command zone. Turn to turn you ramp into value creatures, copy whatever matters most, and snowball card or mana advantage into a combo or grind-out win.
Pick a high-impact Partner (e.g. Tymna the Weaver, Kraum, or Thrasios) to give the deck a real engine and second color reach. Add fast mana like Mana Crypt, Sol Ring, and dorks plus efficient interaction (Mana Drain, Fierce Guardianship) to enable earlier clone-based combos. Lean into a compact win like Thassa's Oracle with Demonic Consultation or Cloudstone loops so Sakashima's copies translate directly into a kill.
