I’m planning to enter a 3G deck tournament with a special rules that only allows Dran blade variants and blades with weight under 35 grams.

I am thinking of Buster, Shark, and Golem Rock.
Dran Buster 1-60 Low Rush
Shark Edge 3-60 Flat
Golem Rock 7-60 Rush

Would this be a good deck?
Tell me if I should swap some parts between the combos or switch some parts.

Thank you!

Those combos should work for the format you are playing under.

SharkEdge 4-60 GF is the best combo for that blade, change my mind.
