Quick explanation of major addition.

This system will be a bit different than anything you saw (i think?), the new resource system does have 2 values that are required to play a card.
- Mana level - the number in a circle - It's your current non empty mana count. (Or full mana crystals from heartstone).
- Mana cost - the count of mana symbols. This resources are needed to play the card and are consumed after.

This is your current Mana Level and Mana symbols available.

- It fixes issue with choosing what mana to pay, because you would pay only the mana symbols.
- It speeds up a game as well, which I was aiming to do anyway.
- The balance probably would need to be adjusted, but more testing is needed.

Mana level as requirement to cast spell, but it only deduced the mana elements from it So just from 5 realms you could cast all spells with mana level from 5 to 1 with if each of them did cost 1 element to cast
