the first time you cast the other. A player loses the game after having been dealt 21 damage from any one of them, not from both of them combined.
in its mana cost, X is considered to be 0.Sakashima of a Thousand Faces lets a blue deck copy another creature it controls while keeping Sakashima's additional abilities. Most notably, the legend rule does not apply to your permanents while that ability is active. This allows multiple same-named legendary creatures to coexist, opening copy-based value plans that ordinary clone effects cannot maintain on their own.
Copying a commander such as Thrasios, Triton Hero can provide another instance of its useful abilities, while copying a creature with an entry effect can generate immediate value. Spark Double and other clone effects can expand the board further once the legend-rule restriction is removed. The best target depends on whether you need another engine, a defensive body, or a specific entry ability.
Sakashima can copy only another creature you control through its own entry choice. It does not automatically borrow the best creature on an opponent's battlefield. It also copies the creature's copiable characteristics rather than its counters, attached Equipment, or temporary boosts, so the resulting creature may be smaller than the current target appears.
Partner offers commander-building flexibility when paired with another eligible partner commander. Within the main deck, Sakashima can support a broader legendary-copy strategy without needing that role. Protecting it can be important if you rely on its legend-rule exception, because removing the effect may force choices among the duplicate legendary permanents that remain under your control.
