i thought it could be costly. vs i thought it can costly.

The correct phrase is "I thought it could be costly." The modal verb "could" is used to express possibility or uncertainty in the past, which is the appropriate context in this case. "I thought it can costly." is incorrect because "can" is not the appropriate modal verb to convey past possibility or uncertainty.
