Well you can have negative death counts (and likely even negative minerals) by adding -1. Possibly to just do it that way. Not sure if starcraft displays negative minerals or would block you from spending negative minerals.

I was going to suggest this. I'm like 98% sure you can have negative minerals (it's been a long time .. )

Oh yes, I just checked. SC displays negative minerals, gas and leaderboard too! Though it treats these values as positive in comparisons in conditions (I checked only Deaths, maybe Accumulate or Score conditions are different?) and truncates overflows with subtract (but allows for overflows with add, hence adding "negative" values works as expected).

So I am to assume that having "negative" amount of minerals isn't the solution here because it's actually a very big positive amount that can be spent for construction.

More testing shows this is wrong. When constructing, SC treats resources as signed integers. For instance, it won't allow to build anything if you got negative minerals. Interesting that SC won't allow to construct anything if you got negative gas, even if the unit's gas cost is 0. Setting negative gas cost (presumably minerals too) is technically possible in editor but doesn't work in SC due to the fact that it seems to interpret cost as 2-byte unsigned integer.

you could do something like buffering the shared resource using DCs.

All players would share one DC.
Players can reserve some amount of DC.
In doing so, the DC pool is decreased and the reserving player's minerals increases by the same amount.
Every interval of time, for all pool's players, if a player who is a part of the pool has at least N minerals, N minerals are removed from that player and N is added to the DC pool.

So something like that I presume would be an approximation of what you want.
