So I did me first battle ever today (plus 3 more) and I have no idea what's going on or what I'm suppose to do. Right now at the start of battle I active my 2 artifacts. Then I press the attack button whenever it pops up and activate my articact when it comes up again. I've gotten two 1st, a 2nd and a 3rd.
Is there anything else I should be doing? I feel that there has to be more to it.

You probably have an impressive list of advancements and/or good artifacts to be getting first that easy 😅
Or perhaps you figured out the right times to play when some other people arent online...

Either way, if youre consistently getting top 3, youre pretty much set in terms of battle.
You can grind it out for some rewards, or stop playing it if you no longer enjoy the WZIB.

If you want to make WZIB more interesting, you can set some challenges for yourself, like trying for as little clicks as possible or something silly like that.
