It states it can't be blocked by creatures with 2 power or less however why is this clause necessary if 'combat damage that would be dealt by creatures you control can't be prevented'. It suggests that when your creatures attack, nothing can block them and prevent the damage?
The ability "Questing Beast can't be blocked by..." on Questing Beast applies only if creatures would block Questing Beast itself (C.R. 611.3a). Creatures other than Questing Beast can be blocked by creatures with power 2 or less as normal. (That ability doesn't say, for example, "Creatures you control can't be blocked by..." or "Creatures can't be blocked by...").
Note also that the ability "Combat damage that would be dealt by creatures you control can't be prevented" applies to such creatures whether they are attacking or blocking.
Also, in case it wasn’t clear, blocking with your creatures isn’t considered “preventing” combat damage for the purposes of this ability. The ability is referring to cards like Fog or Holy Day that specifically mention that they prevent combat damage; Questing Beast is able to render such cards useless. Also, a creature having protection won’t be able to prevent damage as normal, either. For example, a creature with protection from green would still be destroyed if it blocks Questing Beast, as the Beast’s Combat Damage can’t be prevented, which is what protection would normally try to do. This is also because Questing Beast has deathtouch, so any amount of damage that it deals is considered lethal.
Hope you can help with a question on Questing Beast.

Am I misreading something?
