Fun duo builds other than Tornado Shot? HH+MB+300div budget

Looking for suggestions on builds for duo MF farming with my brother, obviously the usual go to is TS, which we've been doing but find it super laggy and that is a problem because even with an aurabot we're not invincible at high juice levels. I'd also just like to try something new and fun.

I've been soloing with fulcrum chieftain and that works fine, it's much less laggy and of course the build is nearly invincible so it doesn't matter anyway, but there's also basically no point playing it duo.

So, has anyone had success with duoing any other combos? I have a pretty budget aurabot right now (pob: https://pobb.in/vWIFxjMK8_sU) but am willing to sink a good chunk more currency into it if that would enable an interesting carry build.

0 button/tanky would be great but idk how possible or effective that is.
