dont worry anon i got you covered

imo some of the best garashir episodes are:

s1.ep3 past prologue

s2.ep5 cardassians

s2.ep22 the wire this is THE episode to watch

s3.ep18 distant voices 

s3.ep20 improbable cause (worth it for the intro but just in general a very very good episode)

s4.ep9 our man bashir another iconic episode

s5. ep14+15 in purgatory’s shadow/by inferno’s light (angsty)

it’s harder to list some of the later episodes because they are plot heavy and only have quick hints of good garashir content (also the writers really tried to play down the dynamic) but those are some good ones
