I need to choose between Giga Drain and Grass Knot to have an offensive against Ground types.
At first thought, I would imagine that most Ground types weigh 50.1 kg or more (making Grass Knot more damaging than Giga Drain), but after analysing a handful of Ground types it seems like only roughly half would actually be heavy enough to take the extra damage from Grass Knot.
Note: I ONLY need the grass attack for Ground types, so the weights of other types aren't really relevant.
My Pokemon will have slow speed so I feel like the slight healing from the Giga Drain would be a useful.
Go with Giga Drain, most Ground types have weak special defenses. Making the special attack Giga Drain that much more damaging. --- OT: Black FC: 1721 2588 4695 Official Metagross of the Pokemon boards
