This. There are a couple of issues with the list:
1) The only allegience you can use is Order, which gives you a battleshock reroll - rendering most of the battleshock tricks from banners etc irrelevant.
2) Your noble champion is listed as having a 'champion's shield' which has no rules. Most bretonnian shields give you rerolls of '1' to save if you charged, but this guy's the one on foot...so it's hard to guess. He has a 3+ save anyway so it could be worse.
They're not a bad list. If an opponent (or
TO) will let you use them, they're pretty good. Stack them with 'generic' general abilities and artefacts and you're good to go.
Grail Knights do
eye-watering amounts of damage to DEATH units on the charge, and anyone who dismisses the army as 'obsolete' will probably change their opinion the first time a grail knight unit rides straight over the top of a formation of skeleton infantry without detectably slowing down....
The Sacred Protector (Green Knight) is incredibly annoying to kill. Give him a phoenix stone, and you've got a 3+ unmodifiable save, plus a 6+ ignore injury (which works on mortal wounds too), plus recover one lost wound a turn, with 5 wounds, for only 200 points. He's irritatingly good at holding stuff up.
