There is no 'best team' in RTA. It's a relatively complicated gamemode where you pick based on the opponent's picks to try to counter them, usually by using the current meta units. This is not something you learn in a day, it takes a lot of RTA matches to get familiar with what works. Posting your box and asking what you should use is not a very useful question as it takes trial and effort to find what works for your account.
It's recommended to check what the meta units are (https://swarena.gg/), and to check other people play rta to see if you can replicate any playstyle. To see others play, you can ask friends, see what streamers use, or simply use the ingame replay tool. In the replay tool, you can sort by specific units to look for.
Once you try a bunch of stuff and find some playstyle and core of units that you are comfortable with, you can ask better questions in #1047269577614164098 like asking which runes/artifacts are recommended for a unit, or you can show a draft you lost so others can give their opinion.
Also remember that RTA is tough endgame content, if you aren't somewhat well farmed in all areas like runes, artifacts, grinds/gems, or are missing key units, it might be too early to focus on RTA. You can still play it to get rewards, but it's not necessary to take a lot of time to optimize your RTA builds yet.
