Well we are talking about Mid Tier here, not high. Level 15 Horsea is a mid-tier pokemon right now. I'd expect Slowbro to be more useful (because let's face it, Seadra is a pretty mediocre shit). Use Amnesia... Amnesia is what makes Slowbro... Slowbro... I'm not sure when/if I'll find time to try, but I think Slowbro should get a fair shot using the moveset: Psychic / Ice Beam / Surf / Amnesia
By the way availability in Seafoam Islands:
Blue: Floor 1 / Level 38 / 1% Encounter
Yellow: Floor 2 / Level 31 / 1% Ecounter
Red: Floor 2 / Level 37 / 1% Encounter
Red: Floor 4 / Level 39 / 4% Encounter
So yeah, Red has the best chance to grab this bad boy, but it's doable in Yellow and Blue. Obviously, bro would be hampered in Yellow (to the point where you'd consider getting a Slowpoke of the same level and getting Amnesia 4 levels earlier). Odds are good that you'll run into one naturally though if you're looking to get Articuno.
Still, if Red (and maybe blue) Slowbro deserves a mid-tier rank (or better!) that should be reflected in the tiering.
"Hmmm... a name for this plan..."
