With 1* player, you could accumulate them all over a few seasons. Bringing 3 x 40%+ 18/19yo (18yo 1-position with SA or 2-position is best, as roughly 1 season’s training will gain a position or SA - next season they can stand in as 20%+ with SA for first 2 cup games and even probably into day 3/4 with weak opponents) into a new season should not impact your draw. 3 seasons on this cycle you’ll have 9 of those, and they will stay for some 10 seasons before you need to replenish any.
Forum would usually have at least 5 platinum associations looking for member replacement at each season end, and typically they look for teams under 110%, or even 100%, for draw purposes too.
What I did in day 1 to 3 of season 4 was:
1) auction checking just past refresh - no interested players then set alarm timer in 7 mins (to come back with 40s for next lot) ; with interested, then set timer in 3 mins;
2) then check associations by random alphabets combination for platinum -
a) preferably Western Europe-based players (timing suits best, as SE-Asian countries would miss late games);
b) English-speaking (with current experience, I would not want to join one without active interactions);
c) preferably 1160 or above (fighting relegation with 1100 or less is tough when first joining - likely to be weakest and not easy also to be expected to keep beating weakest - My asso mates were bailing me out with their wins initially, until I could strengthen properly in season 5 - we barely kept platinum with 1355 and 1370; the pressure of getting at least 2 x 1st or 1 x 1st + 2 x 2nd is a lot

d) can tell if they are active at the time of joining (mine simply demand attendance and bonus - or else kick

) - just quit and rejoin another until such one is found
Good luck in finding your platinum association soon!
