Well, you know the Pokemon I like to use and second, What in the world is a Drizzletoad?
Too bad Swift Swim + Drizzle is illegal now.
No, having a Pokemon with Drizzle (Toed in this case) on the same team with a Pokemon with Swift Swim (Kabutops, Kingdra, Ludi, etc.) is illegal.
Sand Power makes him totally inferior to Landorus, which pulls that off 10 times better due to higher speed, a better movepool (seriously, Rock Polish, Explosion, U-turn, Stone Edge), and a useable Special Attack to OHKO Gliscor with HP Ice with a bit of investment.
Normal gem Gigalith is far from useless trash if you ask me.I dunno if you missed the memo but Explosion is useless trash in Gen V.
