This lure is a little reliant on out-predicting your opponent, but I guess most lures are, so here it goes:
Physically Defensive Colbur Xatu
Toot (Xatu) @ Colbur Berry
Ability: Magic Bounce
EVs: 240 HP / 252 Def / 16 SpA
Bold Nature
- Roost
- Psychic
- Calm Mind
- Signal Beam
Ideally, you find the room to set up a calm mind, as Signal Beam OHKOs at +2, then keep spamming psychic until they switch in Sneasel, which you bop with the Signal Beam. Another option, if you can't set up, is to predict the Sneasel switch-in, hit it with Signal Beam when it comes in and proceed to 2HKO it afterwards. Mostly everyone who I played against so far kept going for knock off instead of Icicle Crash, I guess because it has the better coverage against the switch ins I can make with my team. Xatu EATS Sneasels knockoff with the Colbur Berry. This EV spread gets never OHKO'd by Life Orb'd Icicle Crash, but struggles surviving against Banded Icicle Crashs, so while it is not the safest lure, it is able to put in massive work once you found out what set your enemy is.
