I've got no idea how good star knight really is but I made this
deck so i've got to explain it. The basic idea is to have multiple
high level monsters on the field then deal piercing damage to
your oponent. The card we will be foucusing n when we try to
get out these giants quickly is "Royal Rebel's Phazer".
Phazer can tribute itself to summon a level 7 *or higher* fiend
while you have a level 7 or higher fiend. This can bring back
Pelion, Cheron, Echeclus, or Asbous. Another good thing to note
is that this is not once per turn so we can resurrect many of these
monsters at once.
Next up in this strategy is "Cheron The Star Knight"
Cheron makes our monsters do piercing damage if they are at least
level 5 so we can make our monsters gigantic and attack into our
oponents waek defence monsters to end the game quickly.
we use "Meanacing Eyes Of The Sky Emperor" and "Block Attack"
to switch monsters to defence and exploit them to deal the most
damage.
Finnaly, the last key card is "Evil Star Beacon"
While there are no attack mode monsters on our field this is a double
monster reborn for the normal fiends in the deck like Echleclus or
Nessus. Echleclus is also a level 6 monster so you can boost it
with the rest of the star knights
