practical and tactical genuinely rhyme with impractical (stressed /æk/ + /tɪkəl/); critical, political, logical and typical only share the unstressed ending /ɪkəl/, so they are useful lookalikes but not full rhymes. Note that impracticable /ɪmˈpræktɪkəbəl/ is a spelling lookalike with a different ending.
