This map would been good if you had a better movement system.
I like those kinds of map and you have some stuff to improve.
Replace the summon system you have now with one that automaticly summons them when used.
Right now you have a blink system that does not make you move behind the platforms. I suggest you to take a look on "SoulChess" and maybe use the same movement system as they do.
i think that the map is pretty good but the movement/summon system ruins everything, improve that please.
What about making so that the players can choose their cards befor the match start, that brings up the creativity and the fun in the game.´
One more thing, change the teams you choose when game starts. It requires players to be in atleast two teams, and since i played with a friend i had to put a computer in another team to be able to start the game.
I give the map 2/5 (3.5/5 if you fix the things above).
