mr. e, if you think that agility (or whatever fourth move you run) is so set in stone on zapdos that you'd rather drop twave, i think you should play more rby before making further comments on the subject
Bro, I think you don't know how to read. Bro. Who said anything about dropping T-Wave? I'm confused, bro.
Personally I was just assuming the other move on Zapdos was Rest (STAB attacks obviously being the other two), since it's bulky enough to survive whatever while fishing for free turns against "thing that is paralyzed because everything in RBY gets paralyzed eventually." I guess Reflect is useful for Snorlax, less so against Tauros because you want to T-Wave it first anyway and at that point you're probably better off just throwing Thunderbolts and hoping it dies before it sticks a Body Slam PAR. It doesn't help at all against Goldon since that's a hopeless matchup for Zapdos anyway.
Would you use Reflect + Rest, forgoing T-Wave? It makes Resting safer, but not that much safer since special attackers are the majority in RBY and you still lose the 25% chance of a free turn to burn sleep counters against all attackers (physical too) that weren't already PAR by a teammate. It's a non-Amnesia Lax counter, big whoop. And then there's Agility which you should feel bad about using. Toxic or Mimic if you really want to attempt dealing with Goldon with Zapdos.
Reflect on Zam is necessary if you let it get paralysed; otherwise it gets killed by Tauros/Snorlax/Golem/Rhydon/etc.
Those things don't matter because without Seismic Toss, you're gonna be the one switching Zam out of mirror matches and shit anyway.
That's kinda funny. Toss Zam > Reflect Zam, causing Reflect Zam to switch to Tauros and friends, causing Toss Zam to perhaps resent not having Reflect. Meanwhile, Reflect Zam user is annoyed because he's the one forced to switch in the first place and potentially end up taking a Psychic to the face with something that has like 200 Special and doesn't resist Psychic.
