I figured out how to balance Portal.
Increase the cost of ALL their cards by 1, they early game is too strong because of puppet spam.

REMOVE orchis.
They have gundam why do they get TWO fucking late game wincons??

REMOVE bane.
Why should they get bane when their all their cards are super fucking beefy anyway????

It makes no fucking sense, its like if Swordcraft had all their 1/1 knights with bane at all times, why do they need bane when they have access to such strong beefy cards like aloutte.

Done there you go, I balanced portal.
