Play as Inferno.

There is no build order for the "veteran" difficulty, which is used for most games. The Rift and stables can only be built before the Capitol under certain circumstances; otherwise, you will either run out of money or, more likely, mercury/sulfur.

To be honest, I haven't played as Inferno for a long time, so there might be inaccuracies in the build order; I've already forgotten some details: tavern-cauldron-magistrate-tower-guild of mages-market-kennel. If possible, upgrade the kennel on the very next day; before the castle, it is advisable to build Halls of Temptation. After that, do as you wish.
