Hero/Villan card flip game [wip]

While i take a break from my other card game i decide to do a more simpler card game.

This is a card flip game,(i think) my only card flip game i ever played was memory but i get the approach on how it works.

My game is about a team of heroes and villains, both players can have either of them on their field, how it works is, both players have a deck of cards faced down, they draw 5 cards each and then each player will place down the 5 cards face down on the field, they are free to mulligan any number of cards in their hands and redraw until they get the cards they want but must always have 5 cards in your hand at the end.

after both players have 5 cards face down, they are then all flipped up and what is on the cards will determine the results

Each cards have a score on their cards ranging from 0-600, once revealed both players tally up their total score but the trick is, some cards come with special effects that will affect either you or your opponents cards or the tally at the end of the round.

The lower level cards which are 0 and 100 will have the special effects, 200+ score will have nothing but the score itself.

This will give player strategic approach, do you want to win with big score cards alone or would you risk it by playing the low level cards for their effects.

That is not all both hero and villain effect cards will effect the game different

the hero cards will buff your own score and help your own cards while the villain cards will effect the opponent by giving then negative side effects or lowering their score.

Also there are added bonuses if you play certain cards

if you have 5 heroes only or 5 villains only you get a bonus
5 heroes will give you a total tally score increase while 5 villains will take away your opponent's total tally score.

But that is not all, each hero and villain card will be affiliated to a team name, if you have 5 cards with the same team name on the field you get special bonus like example increase total tally or select 1 card on your side of the field and you are able to use it again on the next round.

That is basically what i have so far, I am currently working on the cards effects right now

Im making this game to be like a quick 5 minute each round, i haven't decided on how a player wins the whole game either playing a certain amount of rounds before tallying all the cards score that has been won by the player. if you lose a round, that scores round doesn't count for you so only the winner of each round will be able to tally up their total score at the end of the game

Or when the players run out of cards to draw and whoever won the most points from their victory rounds will win the whole game
