Im building a team in Pokemon Showdown to hopefully build in Sword. I feel like all I need now is a wall Pokemon to resist fire and rock, since most of my team is weak to fire, and my core Pokemon is weak to rock and my only rock resist is 4x weak to fighting, so I'm worried that it could easily lose to superpower t-tar. Any ideas on a good rock/fire resist 'mon?
(If your wondering, my core Pokemon is Galarian Darmanitan. The other Pokemon mentioned here is my rock resist, which is Bisharp)
