2nd round is always easy with GB/IK chain, and Yosuke/Mitsuru/etc can just cheap the first round out with their FA. But characters like Naoto (FA is too unsafe to use often; a whiff will screw Naoto over so hard) and Liz (trash FA) have to use alternative strategies. It's easy in theory, so the challenge comes from evading them, especially Mitsuru and Chie as they can end you in an instant.
Especially Chie and her 9k raw God's Hand.

Geez, how much money did Noboru have?
