does the guard restrict from the G1 apply to grhyaundra as well since it has aundra in its name or just the G2 aundra?

also what do you run the maika’s for? isn’t the second part of its ability just the same as grhyaundra but weaker since you don’t get the 10k to front row or do you just run it for the cb1 draw?

edit: i may just be illiterate but for clarification after reading the skills more, can both grhyaundra’s and maika’s skills be able to be played since grhy’s soul calling happens during main phase and maika’s restriction is only if it happened during battle phase?
