Ok, so I built it up in two turns, just to get it back is not good in Sablelock.
Honchkrow is way better, as it OHKOs the Gyarados and probably stays alive to get another prize.
Drifblim shuffles it into the deck and the oppenent might get another Gyarados running, not very good, because then they will easily take and advantage as I am NOT ABLE to OHKO their Gyarados, definitly NOT GOOD in Sablelock.
Maybe in LuxChomp, but LuxChomp just wins, because they can OHKO the Gyarados!!!!
Against Machamp I would also have to play Lucario GL, which would be a death card outside of the Machamp MU and Drifblim doesn't stay alive as long as Honchkrow against Machamp, so that would also be not as good as Honchkrow.
You have to always try to get the seeker, see they always gat a prize or you can turn your active Pokemon to do that or even know when they got it with drawers or something like that, however you just have to wait for it and have a good timing.
