If I have K'rrik, Son of Yawgmoth out and cast Vraska, Betrayal's sting, spending life for the phyrexian mana symbol, can I elect to have her enter with her full loyalty by electing to pay 2 life using K'rrik's abiliy rather than the 2 life mode for phyrexian mana? Or does Compleated only care if I spent life for that mana symbol, and not how I did so?
Compleated only very specifically cares if you chose the inherent life payment option for the card's Phyrexian mana symbols. If you pay life to cast the card in other ways, such as through K'rrik or Bolas's Citadel, the planswalker will enter the battlefield with its printed starting loyalty. The loyalty reduction is specifically linked to how you pay that phyrexian mana symbol. If you don't pay it somehow, then there's no loyalty reduction.
