Well, fighting or Ground has the best SE coverage, being super effective against five types (Rocks, Ice and Fire are right behind with four).What is the best attacking type by means of super-effective coverage? And I say that, as some people would say Dragon because of it's almost perfect neutrality.
Ghost/Fighting has a perfect neutral coverage within two moves, something Dragon moves can't have: Blame Heatran for being immune to Fire due its ability. Dragon/Fire technically has neutral coverage, but only on Reshiram, who ignores Heatran's ability.
And as I have corrected, Ground/Ice offers the best SE coverage on single types; unfortunately some Rotom forms ruins the fun because of Levitate. If you don't want to deal with immunities stick on Rock/Bug (which I personally find ridiculous).
Actually Dragon/Fighting has perfect neutral coverage.
So right - though there isn't a fightin Pokemon who have access to both powerful Fighting AND Dragon moves. Probably Dragonite with Outrage/Superpower, when we are willing to drop Multiscale.Actually Dragon/Fighting has perfect neutral coverage.
EDIT: Does magic coat beat out prankster?
What about Kyurem? And is the combination of MixApe+AgiliGross effective?
Kyurem is outclassed by Latios if you are going fully special, Salamence if you are going mixed, and Dnite if you are going fully physical. I would only recommend it on hail teams or multiple dragon teams
Dragon moves without STAB hasn't been really amazing; they lack either the power or the "super-effective" coverage. I even dare to say, Draco Meteor is redundant in the face of the stronger Psychic, because it's neutral coverage isn't much worse. The additionaly damage Reuniculs and Tyranitar take is pathetic after the drop of your SPAtk.Would Draco Meteor on Jirachi ever be useful?
What Pokemon are good in setting-up Stealth Rock? Could I, for example, use it as a filler move on Mamoswine, like Heatran does with the Air Balloon set?
