In all honesty, I'm curious about why more people aren't using Hippowdon over TTar. Could it be because TTar has higher defenses? A Rock and Dark STAB? I don't know the big reason behind it, but Hippowdon just seems better than TTar. The only weather starter with a reliable recovery move; the lack of a Fighting, Ground, Bug, and Bullet/Mach Punch weakness; more viability as a TR pokemon; these are all great advantages to have. The Ice weakness is a pain, but Abomasnow is the only popular Ice type it needs to watch out for since Weavile can't really put any dents in it huge enough to 2HKO Sitrus Berry variants w/o an Expert Belt, and even then, there's his partners to worry about and his recovery move if he uses it. There's also the truth that most popular VGC pokemon with Ice moves are Water types more willing to use their STABs to kill the bulky hippo.
Long story short: Unless you really need to wall special attacks or need the speed of the Scarf set, TTar is generally outclassed by Hippowdon.
Weakening psychic type attacks isn't very effective because there isnt that huge of a presence of psychic type moves in VGC.
There are no legitimate female DW starters, so none of them can legally have egg moves.
Except they can only learn it through an egg move or 4th gen TM, neither of which are possible with Chlorophyll.cant you get a bulbasaur or ivysaur and teach it giga drain?
when?Care to try it out against mine on Pokemon Online?
