[Modern] Magmatic Sinkhole
This is a potential sideboard card for us and could be a candidate to replace Path. It isn't a good early answer for creatures, but it can kill a lot of big things (up to Gurmag). It can also kill planeswalkers that might be in use (like Teyo).

Edit: I should have clarified what I mean by replacement. Boros won't cut path for this. This provides something for non-white lists and provides something if Burn shifts away from white some day (perhaps if Fireblast got printed and we need enough mountains to make it work, but don't want 4 Foundry).
