Why aren't more of the normal set spacecrafts like this, where you play them, tap a couple creatures, and get a pretty strong ability? Maybe even crew it later on, if you're feeling risky. Instead, most of them are just a spell-on-a-stick that you can permanently crew for value afterwards. The only two that come close are the "when you attack, do way too much damage to target creature" and the "your tapped legends are indestructible" ones, which are still mostly just really expensive vehicles.
