Round 2 of attempts to earning chests, have any suggestions? (Read before commenting)

Well i got S ranks with Cho'gath(still lost but won the war) Support and Sejuani Support. Need to still try and get 2 more S ranks for chests, between all the champions below can you guys include ideas for the following:

-What game mode would you suggest using the champion in for a 'good chance at getting a S rank with them, preferably in using them in a off-meta style' -What role would said off-meta that would allow the champion to still work and allow that champion to work, please explain yourselves then just saying 'lulz play anything in support'. -PLEASE do not repeat the repetitive advice of 'ward more', 'die less' and what not, just like my first post i rather avoid clogging the thread with the same 'common' replies, i would prefer if you have any good suggestions beyond the 'norm', to say those instead of repeating the same thing everyone else says.

Anyone with the champions below, do you guys have any good (and actually works, no trolling posts) suggestions?

Though i guess 'regular' picks for the 'normal use' is fine, but again a preferred explanation and preferable the reason why you said to try champion X in lane 1 and preferable with it not being something overcomplicated or works.
