Notes: Alolan Dugtrio stands out as the only Steel / Ground type in ZU, granting it two useful immunities. With a base 110 Speed, it ties with Raichu while outpacing offensive threats such as Rapidash, Kadabra, and even +1 Combusken. Substitute + Toxic is arguably its best set, being able to cripple defensive checks for its teammates while Iron Head + Earthquake provide solid neutral coverage in the tier.
