Walking Wake @ Choice Specs
Ability: Protosynthesis
Tera Type: Water
EVs: 4 HP / 252 SpA / 252 Spe
Modest Nature
- Hydro Steam
- Draco Meteor
- Flamethrower
- Dragon Pulse
Just mash Draco Meteor and Iron Hands should go down in 2 hits thanks to packing Tera Flying instead of Tera Fairy. About the only ways Iron Hands can avoid this 2HKO are if at least one Draco Meteor misses or if Walking Wake low rolls both times and Iron Hands gets a decent roll with Drain Punch - and all such chances are erased in Sun, which upgrades Draco Meteor to an OHKO and Hydro Steam to a near-guaranteed OHKO. The Modest variant 2HKOes Blissey most of the time with Tera Water Hydro Steam in Sun and is favoured by the occasional OU Sun team.

Impish Nature
- Stealth Rock

Yes, OU is desperate - occasionally desperate enough to run Quagsire on a stall team. The 4th move is to KO Tera Flying Iron Hands eventually (Drain Punch basically makes Liquidation unable to net injure Iron Hands).
