the existence of synergies makes the optimal strategy much less rng focused by allowing multiple options to hone their strategy. Also, increasing the base value of ores with a lesser increase in the amount of base ore scaling encourages multiplicative scaling in the early game, as opposed to additive scaling which would previously be best for the first few rounds.
also, I like the new ore synergy! and making wrench scale on tools makes it much more interesting, since it is no longer naturally synergetic with actions (typically most actions give energy and card draw). similar things can be said about waterfall.
