Sakura summer is the perfect support for water main. If you own madara 5th summit that's by itself an op team. Is also good for any immortal team. Angel konan to work requires a good move 1 and some huge support like kisame samehada and minato hokage. She is, de facto, an high power toy, like edo hiruzen. So if you go more for collection and for funny arena teams, imho is better to get sakura.
