But also, they would take damage from Bursting Balloon and between 4 stadiums and a Field Blower you should be able to take out their Rough Seas. If they have all their Lapras's on the Bench, and they took damage from Team Magma's Base and one Tapu Koko attack they will have 10 damage all over the bench, and then when they attack into a Balloon they'll have 80 damage which takes three turns to heal off and the total of 120 damage per turn from Honchkrow, Lapras isnt an autoloss. Rough Seas will slow you down but it won't finish you completely.
You may be able to take out a few of their Rough Seas, but as long as they can hunt it down during their turn they will be healing. Add that to the energy denial structure of Quad Lapras, and Fighting Fury Belt, and it's going to be a really rough match up for this deck.
