Unnamed TCG game

My tcg game is about player cards that acts as factions and troop cards that help defend the faction card, the first faction card reaches 0 life points loses. What is great about the faction system is multiple players can play at once in an all out faction war. Currently this is what i have come up with

I appreciate if i can get some ideas added to the game, but since my mechanic is set i dont really want to hear, TCG type game wont be good or there is no market for this type of game, i get it but if its the type of thing i enjoy then i would like to see it through

So here we go

Unnamed TCG

Faction card
4 available factions are at launch, each faction has a special ability that differentiates from each other.
Players choose a faction to represent themselves, then players choose troop and spell cards to act as the faction's defence. Players need to draw resource food cards so they can spend the food to play troop monsters.

The faction cards is the players life points, once it reaches 0 that player loses. (life points are not set but an example would be 1500 LP)
The faction cards have numbered abilities 1, 2, 3, each turn on the players turn a counter is placed (max 3) on the lowest number first, each passing turn that player can put another counter on the 2 and 3. The player is free to spend the counters on either 1, 2 or 3 on their turn to activate an ability which could alter or change the battle around. Once an ability has been used, the counters are removed from the card and the card returns to 0 points and you must then power up the cards again during your own turns.

Region cards
Each deck can have region cards, you are able to play 2 region cards at a time, they are used to power up your troop or give you an advantage in battle, and they remain on your field until you replace the regions or the opponent destroys it.

Region cards (All may not be available at launch)
The monster associated with that region are only affected by that regions ability. The regions abilities are still WIP

Swamp

Volcano – Burn: Once per turn on your turn only flip 3 coins, if heads all enemy troops that are not associated with volcano receives 20 damage X number of heads.

4 tokens, result 1,3,4,6. Enemy misses attack
5 tokens, result 1,3,4,5,6. Enemy misses attack

If you don’t think some creatures belong to the right region or faction or if you can come up with some more creature species ill appreciate the help

Resource
Each deck will have a certain amount of resource cards which are in the form of food, they are used to play troops onto the field, some require 1 will others require 4 or more( you would need food for your troops when in battle right? So I thought this is a appropriate mechanic )

I was thinking of adding different food sources for different factions since some that eat meat is illogical so one food source is find for this game. Most food cards will only contain 1 food while some cards will probably have 4+ food. I haven’t fully decide on if food cards are used they will be discarded or the ones that are played will have a cool down on it so you cant use the ones you played until a turn or so has passed like in magic, the mana cards are replenished on your next turn.

Spell cards
These cards acts as attachment cards for your troops which will power their attack or defence or have a special ability. Some cards will probably only be used on certain troops for example: I can only play bone club spell attachment on my orc troop which will boost its attack by 20 or something.
Attachment cards will stay on the troop until it is forcibly removed or the troop dies.
Other spell cards I coincided are counter cards and cards that affect the opponent.
