Between both Stel and Secad telling me I should train a tropius, I've decided to XD I'm probably going to go with a more defense based set, but this is every set I could come up with Physical Chlorophyll attacker Tropius@Yache Berry [weakens ice attacks] Adamant Nature Chlorophyll ability Sunny Day / Swords Dance Earthquake Leaf Blade Aerial Ace With a Base attack of 68, might not do so hot, but I'm trying to come up with and weigh everything I can. Swords Dance is a possibility with this set, probably in place of Sunny Day, but without the speed boost, I'd worry that it wouldn't even get to perform it's duties... I've been thinking about a Castform which would entirely solve that problem. EVs in attack and speed. Special Chlorophyll attacker Tropius@Yache Berry [weakens ice attacks] Modest Nature Chlorophyll ability Sunny Day Solarbeam Air Slash Hidden Power Fire / Silver Wind Only 72 special attack, but with Hidden Power Fire, it could do a pretty good job, without it, I'd be hoping to flinch or get lucky off of Silver Wind. Special attack and Speed EVs. Full-out Solar Power set Tropius@Life Orb/Wise Glasses Modest Nature Solar Power ability Solarbeam Air Slash Hidden Power Fire / Synthesis Silver Wind More than 520 special attack with the Life Orb, and about 440 with Wise Glasses. requires something else to set up the Sunny Day, and probably isn't worth it without the right Hidden power. Life Orb means it'll be losing HP faster than if it was hit with a status effect, so it probably won't get more than two attacks out before fainting. EVs either full special attack and speed [could help with some pokemon] or split defenses and full special attack. Wallish Solar Power set Tropius@Heat Rock Modest Nature Solar Power ability Sunny Day Synthesis/Roost Solarbeam Hidden Power Fire / Air Slash / Silver Wind Roost eliminates the rock weakness, lowers the weakness to ice, gives back the electric resistance, though I'll drop the fighting resistance, and ground immunity becomes a resistance. Seems like a decent trade off for restoring half of its health, no? I don't know if I lose the STAB on Air Slash, but it's safe to assume so, and with this tropius as slow as it is, I'd prefer hidden Power Fire even if it did still get STAB. HP Fire offers better coverage and gets the equivalent of STAB from Sunny Day [leaves it horribly open to fire types, however]. Synthesis offers a full heal in place of the trade off with Roost, and Solar power working against me with attacks coming at me, Synthesis may be the better choice. EVs will be split between defenses and full Special attack, or 170 EVs in each. Leech Seeder Tropius@Big Root/Leftovers Bold or Calm nature Chlorophyll ability Leech Seed Roost / Protect Substitute / Toxic Air Slash Chlorophyll for a speed boost should sunny day come into effect with another pokemon and because Solar Power would be nothing but harmful if it came into play. Air Slash offers Grass coverage, which is really all it needs to go with Leech Seed. Roost restores HP, should Leech seed alone not be enough, and it also gives the trade-off I mentioned above. Toxic to speed up the killing process, which could be better combined with protect than roost. Substitute would prevent status, and I'd most likely be using it when whatever I'm fighting is about to die, so the switch in can't hit me directly yet. Many choices with this set, and it seems like the best for Tropius, given its stats. EVs in Defense and Special Defense, none in HP to further benefit Leech Seed, but I might put the extra 6 in it to aide with an extra substitute.
