@Anon1 That’s why this deck runs a couple Galaxy Explorations. To play around graveyard locks to get out your Xyz monsters.
@Anon2 Don’t act like none of the other tiered decks aren’t skill reliant.
It's kinda sucks that you have to rely normal summoning Galaxy wizard and one Galaxy expidition on your opening hand tho. Can't do the search since you have to tribute it. So you'll leave no monster onboard.
I play infernoids and I'm pretty sure all Galaxy decks I've faced have surrendered. I just banish their Galaxy-Eyes and it's gg. So I'd say anything that messes with the graveyard, especially losing access to the Galaxy-Eyes.
