Protect

Protect is a Watcher common skill that gains 8 Block and has the Retain keyword for 2 energy. Retain allows it to persist in hand between turns if not played, making it a flexible defensive card that you can hold until you need it. The 8 Block is a solid defensive value, and the ability to save it for the turn you need it most means Protect is always useful. You can draw it early, hold it while you make offensive plays, and use it when a threatening attack is incoming.

Protect fits naturally into Watcher decks that need reliable, plannable defense. Because it Retains, it doesn't create dead hands when drawn on turns you don't need Block. The 2-energy cost is relatively high for a Block-only card, but the Retain quality justifies the cost by ensuring it's never wasted. It works well in Calm-cycling builds that need Block backup when cycling isn't optimal. Upgraded, Protect gains 11 Block instead of 8, improving the defensive return significantly for the same energy cost.
