No offense but i think you need to think about your deck construction more if you can only win with wrenches they are really not that op compared to other top teir strats wrenches are good dont get me wrong but action combo strats just as good imo. Something that might help you if you have a ton of tools in your deck it is probably a good idea to take a few gems in the lategame for good resources and drawing
I literally did not say that. I have won multiple times on brutal without wrenches. But it requires a lot more luck - luck that the shop will give you the cards you need (with very little tolerance, most attempts fail because shop just never gives you enough) and luck that the large deck in midgame wont screw you with a bad deal that ends the game early.
Wrenches do not have this problem.
e.g. won like this multple times - after wrenches, axes still dominate the game due to balancing issues (better to be able to shoot through the deck fast, since the game doesnt let you keep cards in hand and decide when to play them. This is the core balancing problem: player has very little control, so things that make up for the lack of control win much more often)
Card draw will always be strong in deck building games, especially in games like this where you stack all your upgrades on individual cards. Drawing your key cards more often is just makes sense. Axe isnt your only drawing option, mineshaft is a strong card (10-10 for 1 and refunds the energy and draws if in a action combo) and builds together quite well with minecarts (3-3 draw 2 cards cost 1 refunds itself if used in a action combo) compass plays well with these cards situationally it can be better then axe. Axe is by no means a bad card in fact it is quite strong but it also needs your deck to be strong to be good, in the first store i would take pickaxe, mineshaft even mybestfriend (the 15ore actioncard) and screwdriver before i would take axe
