So this is tough because there is no village. However, I am confident that workshop/gardens is bad. I would open watchtower/silver, and get goons ASAP. Take goons over gold for a while, you want to be playing one every turn. Watchtower is good for topdecking your buys, and if you have an extra buy from goons, trashing a copper or curse but still get the goons point. It also draws 4 cards if you are hit by goons, but play goons if you can anyway. You will want to wait a while before greening, and you may want to go for gardens a bit at the end depending on what your deck looks like.
Also of note is that your kingdom has only 9 cards. Colony does not count as a kingdom card. You choose 10 kingdom cards, then decide whether to add Colony AND Platinum (they go together) by choosing a random kingdom card and checking if it is from prosperity.
