In Stadium, the user becomes uncontrollable during its next turn. Otherwise, the user attacks on turn one but it doesn't recharge on turn two if it KOs the target, breaks its Substitute or misses entirely.
Other Options: Nothing that takes precedence over the above four moves: Thunderbolt, lame OHKOs, etc.
Verdict: This set may seem redundant but it is extremely good and has made Tauros quite common in the RBY metagame. Body Slam can paralyze a lot of things, especially by catching them off guard on the switch, and then Hyper Beam finishes them off. Earthquake can hit Rocks while Blizzard can hit Rocks and Flyers. These are the only four moves that Tauros really needs to sweep, and it's unsurprising that he remains one of the few Physical Attackers who sees any use in RBY due to his high-threat level.
