Welcome to Reviewing the Little Boot Icon, an unfortunately named series of reviews for Reboot-modified cards. Today's review: Rainbow, the only barrier that is also a code gate and a sentry.

• Changes: Strength 4<5.

• Pros: Excellent strength-to-cost ratio. Neutral, so any deck can play this. 5 strength annoys basically any breaker.

• Cons: Weak to D4v1d. Any breaker can break this (with Datasucker tokens) except Deus X, Gingerbread and Sharpshooter.

6/10 Good in decks that just want to tax late-game and bounce early-game.
