As someone who genuinely wants them to suceed i will try gugvung sum stuff they could do especially comps wise.
Imo theyre biggest mistakes were to not perma ban icebox after the 1st or even 2nd time they played it so what i would do is just perma ban that map, youve shown ur not good at it. The other mistake was trying to adapt to a different meta(tejo) than the one you yourself had already discovered and embraced(double duelist iso in particular) so here is what i would do with theyre maps in terms of comps.
Icebox-perma ban (i explained why above)
Sunset-play sum kind of doubele duelist, i would favor yoru raze
Lotus-either stick with ur own iso comp or play the prx one with yoru iso
Haven-just stick with urs, its probably the best on that map rn
Split-just play ur own yoru raze and copy some of the eu teams strats
Pearl-stixk with urs or actually just copy the c9 comp which has cypher yoru and jett
Ascent-interesting one but i want them to play double senti with cypher-deadlock (just switch izu and meteor around on the 2) and put some discipline into meteor cuz he cant just play how he plays on split there
TLDR: Pick more double duelist, double senti on ascent and perma ban icebox
Have a wonderful day
