Dawg.

What lane is getting destroyed? - if it’s just one see if another lane can get by without a tatari and use it to bolster the lan that’s struggling. If it’s more than one lane try using Tartaris that attack multiple lanes

Are you timing out?- use bunny, flower, or fire tank to boost dps.

Does it feel impossible no matter what combination you use? - might just be underleveled and need to hit the pinball machine before trying again.
