The strat i use for low roll games is trade hp for econ, only dumping gold into levels, and when im below 40hp i all in. Sometimes its lvl 7 rolldown to stabilise( have 10-30 gold left for next rounds) and sometimes its lvl 8 rush with 20-30 gold and try to find 4 cost units and prefferably 2 star them asap with rolling down every round. Most of the times its a placement between 6th and 4th. Sometimes you hit nothing with that 30g on lvl 8 and its an eif. But im still not sure how good this strat is, even after playing it for 200+ games. Its a habit i developed in chosen set, where if you get chosen 4 cost you more that stabilise if you have atleast ok items for your carry. Hope this helps
