The UU analysis saysSpread for Subroost Kyurem?
EVs: 56 HP / 220 SpA / 232 Spe
"The given HP EVs allow Kyurem to make 101 HP Substitutes, preventing Blissey from breaking its Substitutes with a single Seismic Toss. 232 Speed EVs and a Timid nature are necessary to outspeed Jolly Krookodile."
So I suppose you can drop a couple EVs from Speed for LandoT instead of Krookodile and just put them into SpA, so it'd probably look like this: EVs: 52 HP / 232 SpA / 224 Spe
