Knight of Reliquary + Maze of Ith

[alphacat]

I'm wondering if it is possible to declare Knight as a blocker, then fetch Maze to untap another attacking creature, thus, nullifying two attacking creatures.

Also, are there any other combat tricks associated with Knight that is commonly used?

Yes, you can do the blocking trick to have both attackers become "blocked".

Another trick you can do is attack with a creature, then in the End of Combat step, use Maze of Ith after damage has been dealt to untap your attacker.

You can do this. Also, in addition to what Rukcus said, you can do really stupid stuff with a Sword of Feast and Famine tossed in, like attacking with a SOFF'd Knight, Mazing him with the SOFF trigger on the stack, and getting to untap the Maze with the attack.
