Not sure how to build Galadriel but only Elf Tribal. I also have Ezuri and thought of making it an Elf Tribal but it works better not being an Elf Tribal, for me.
#Galadriel vs Ezuri +1 counters
gritty mirage
median charm
if you are looking for directions to possibly go you can look up galadriel on edhrec's website. I think a logical direction to take it is blink and ramp +1/+1 counters deck.
