My solution

Written in Snobol4 and compiled with The Macro Implementation of SNOBOL4 in C (CSNOBOL4) Version 1.5 by Philip L. Budne, October 1, 2013. SNOBOL4 (Version 3.11, May 19, 1975), Bell Telephone Laboratories.

    i = 5
    arr = array(i)
    arr<1> = 'A♦'
    arr<2> = 'K♦'
    arr<3> = 'Q♦'
    arr<4> = 'J♦'
    arr<5> = '10♦'

lp  ge(i, 1)          :f(end)
    output = arr<i>
    i = i - 1         :(lp)

end

Output
