Onslaught can open up some interesting possibilities so I feel you will like this guide here – please mind, this guide here is getting the good decks directly from my popular meta decks list and gets updated each time I update my meta decks (at last once or twice per week), so you will never find any outdated decks here that are not flagged as old and outdated.

Onslaught in the current meta: Not on top of the meta but as long as you have strong cards with ongoing effects running well, he kind-of has a spot in there, too..

Good Synergies with Onslaught

Zoo Cards work well with Onslaught as he will double the effect on the same location so you can scale a lot higher with them. Read more about playing Zoo Cards here.
Iron Mans ability can be doubled (so basically four times the power at that location). You can basically play Onslaught and Iron Man at one location and already have 28 power there. Read more about playing Iron Man here.
Klaw can buff up the location next to him through an ongoing effect and you can use Onslaught to make that +12 power to the location next to Klaw. Read more about playing Klaw here.
Devil Dinosaur gains his extra power threough an ongoing effect and you can double that with Onslaught. Still, Devil Dinosaur is normally strong enough in one location but it can sometimes work and as you normally play him with other ongoing cards the deck synergy helps.
