Grim Monolith looks helpful with the Sol Land ramp.
Even with that more combo-focused list, I still recommend trying 4
Patchwork Automaton in your deck. The card is extremely powerful and enables fast "fair" wins when you aren't able to assemble Syr Ginger + Mystic Forge, growing even faster than Syr Ginger. It adds an extra layer of resilience & another "bot" threat even more explosive than Salvage Titan. When Forge does go off, it still makes Patchwork grow at an insane rate for free. I made 30/30s and bigger. Ward 2 is relevant text. The bot is much harder to kill than Dreadnought and easier to enable.
The 2 cmc is a bit awkward when going off with Forge, but Syr Ginger can scry extras away easily. Imho lands are worse reveals. Automaton could replace Frogmite?
