So you give the enemy a 4x weakness. It is a pretty good strategy. Only one problem: neither Phantump nor Trevenant can learn fire attacks that go with this. Sure they can learn Will-O-Wisp, but that is hopefully going to be an attack that just burns instead of being a ridiculously OP move that can kill Reshirams with one use. Trick-Or-Treat, pretty useful. Forest's Curse, technically pointless due to the only two Pokemon that can learn it (unless if you want to be a scumbag and teach it to Smeargle). The only use it can have offensively is by teaming up with a Fire-Type and use it so that Fire-Type can kill the enemy easier. In a 1v1 situation, there's no point having it.
