An “Iniative” game mechanic [closed]

This challenge is inspired by turn based videogames like "Heroes of Might and Magic"

Implement this game mechanic:

• There is some units(Imps, Swordsmans etc...) in our game
• Every unit have an integer "initiative"
• Your program must decide which unit's turn now - based on unit's initiative
• The more initiative means more frequent turns(for example unit with 10 iniative will move 5 times more often than 2 iniative unit)
• Unit with highest initiative moves first
• Input: Array of pairs of [unit_name: string, unit_initiative: integer]
• Output: Unit names in moving sequence separated by line break (\n)
• Make 50 turns total

Test case:

Units: [["Imp", 500], ["Mammoth", 50], ["Swordsman", 250], ["Elf", 350]]

turn sequence(50 turns) output:

Imp
Elf

Other rules:

• Write shortest code possible
• Attach a link to an online iterpreter
• Welcome to the site. You need to provide an objective scoring criterion. From the ‘other rules’ bit, I assume you’re intending to make this a code golf challenge, so this should be tagged as such. The usual scoring for code golf is bytes. Optional challenges don’t tend to work because if you’re optimising code length you’ll ignore the optional challenges. – Nick Kennedy Nov 30 '19 at 10:27
• To add on, the optional challenges are also a problem since they look like they can be interpreted in a way that trivializes the task. They are very vague as to what they require so you might, remove all the units on the first turn, to avoid doing any computation, and say that this is fulfilling the first optional task. – Ad Hoc Garf Hunter Nov 30 '19 at 13:51
• Inputs and outputs specified; Optional challenges removed; "Write shortest code possible" added to "Other rules"; – Rundom Dec 2 '19 at 9:44
• Thanks for taking the time to fix the challenge. I am still unsure of the task. A couple of questions I have are: What sort of order is required if any? for example in your example could I just give Imp 500 turns in a row, then the elf 350, then the swordsman 250, then the mammoth 50 and then repeat? Or do I have to do some specific order? Or is there a rule that the order must follow? In order for this to be clear it must be possible to look at the output of a program on given inputs and objectively determine whether that program is valid. – Ad Hoc Garf Hunter Dec 2 '19 at 14:18

This version is one bytes shorter but I expect may sometimes get the order wrong because of inaccuracies in floating point calculations.
