Goblin psychic challange battle score cards (power calculation)

I tried to quantify how powerfull monsters are.
This can also be applied to score what monsters added to the fight!

Unicorn: tanked like a boss, void soaked up 7 damage so this is added to his monsters power.
Queen mycelia: negated 1 attack on the unicorn, 3 health is added this this monsters value.
Knmer princess: was there dished out some damage, nothing special.
Goblin psychic: healed Unicorn for 9 health. absolute MVP.
Spirit hoarder: nobody in the back-line got hurt, so no points for him.
Regal peryon: i know technically he did as much as Knmer princess and Spirit hoarder (for more mana cost!). But he gets automattically a higher score due his off-tank capability against melee damage dealers.
But that was not needed in this battle, this calculation might need some tweeking.

The rules to calculate monster power so far:

• 1 health is 1 monster power.
• 1 armor is 2 monster power any additional armor is worth 0.5 monster power.
• 1 Speed is 0.5 monster power.
• 1 attack is 0 monster power,
• 2 attack is 2 monster power,
• 3 attack is 3.5 monster power any additional attack is worth 0.5 monster power.
• Ranged monsters are worth 2 additional monster power.
• Ranged monsters are worth 4 additional monster power.

Afther this there is a manacost correction and score normalisation.

This is a work in progress:

• part 1 (melee)
• part 2 (ranged)
• part 3 (magic)
• part 4 (shield)

The victory is nothing special, just me having better monsters.
But i thought it was insightfull trying to value the monsters after battle.
