Tahm Kench [support] Summoners

What are the best spells in general to run on Tahm Kench as support? I know it can depend on the situation but most of the time I feel like people say the normal are what you ideally want to take. To me it seems like would be a much more suitable alternative in low ranks (i'm in high bronze-low silver) because you can use it with an ally (only) to escape a lot easier in sticky situations that low rank players tend to put themselves in. What do you think? Perhaps even ?
