This seems like an intresting concept, so i think ill help work on the mechanics of the card game and such
a normal "deck" would contain 40 "Monster" Cards, 20 "Buildings" Cards, 20 "status" cards, 15 "Add-on" Cards and One "Admin" card
A monster would be a blocklander, using either Melee, Magic, Range, or Other, having HP, ATK, DEF, POWER LEVEL, and BRICK COUNT
POWER LEVELS would be on a scale of 0-10, 0 being the lowest, 10 being the highest.
BRICK COUNT would be how many bricks it costs, and how many Baseplates it takes up.
A Building card would be a structure made of bricks, costing BRICK COUNT and Baseplates but might add more BASEPLATES or BRICKCOUNT/per turn
At the start of the game you start with 5000/5000 HP, Having 500 BRICK COUNT, 2 BASEPLATES and gaining 50BRICKCOUNT/turn
A Status card can change the way a game goes, ranging from slowing your brick income to increasing your BASEPLATES 10 fold
But of course, the drawbacks would be it costs a good ammount of BRICK COUNT and would not let you attack in your turn.
A Admin card is basicly a god card. Either Badspot, Kompressor, Kalphiter, Ephi, all 10/10 POWER LEVEL and have an attack based on however many monsters/BRICK COUNT the other has.
Add-on cards are well, add-ons, to increase ATK/DEF/POWER LEVEL/HP they take up BASEPLATES and decrease your BRICK COUNT income slightly.
