First time trying out cube, to be honest i think cube is kinda meh even though i won with it I feel like overall its kinda weak because to work it needs tool support and other ores have comparable upsides or are better ( the +1 per upgrade seams to be similar numbers while not needing tool support, score pando has ore that also kinda scales with it, kaz support is stuff you basically always want anyways meteors and geodes and draw). Drill theoretically has good synergy with it but every time you use it you arnt going to have energy to upgrade the cube and feels bad to not upgrade it and also has its on energy issues that are harder to resolve because you cant cheat it out with a tool so you basically need a super thin deck or get really lucky with the most expensive card in the game? minecart. Corkscrew in theory works well with it to but corkscrew feels to similar to prospect for me to really want to add it, and seams like it would make prospect turn into a brick knowing theres a better version in my deck
