Actually no. Let's say a 9 HP Icebeam blast, then count in double weakness. I would give it 17HP, Spade decides on 18HP. Small difference.

Ore: Wait until after the Gigadrain, then use Avalanche on Buzzer! Another Icebeam (Buzzer). Then finish with Zen Headbutt on Squish.

Lucian: Finish him with boosted Sp.atk. Psychic x3! (Squish)
