This is Alfred. He is known as the King of not only the Royal Paladins, but the whole United Sanctuary (starting season 3, I don't think he's still King). In my eyes, it's a popular card.
Use this as as your vanguard, or backup in some decks.
Strategies and game play:
Sincce he can't be boosted, don't put in Marron or Pongal behind him. Try Lien or Margal or Barcgal. Alfred has amazing synergy with Gigantech Charger. A nifty little combo is calling Gigantech Charger, checking the top card and if it's an attacker, put it in the front row on the opposite side of Charger; if it's a booster of 7000 power or higher, put it behind Charger to get him to a stage 2 attack; and if it's a weak booster choose any backrow arbitrarily. Then rest Barcgal, call Flogal to an open booster position. Finally, use Alfred's counterblast to call whatever you happen to be missing (boster/interceptor). Try to keep all of you Rear-Guard attackers around the 16000 power mark if possible. This sets you up so fast and strongly, it's ridiculous. You'll take note that Alfred is now at 20000, his maximum power.
Combos with other cards:
Lake Maiden, Lien
Ways to counteract it:
Try retiring some of the rear-guards to make the user call again, lose cards, and of course, making Alfred below 20000. This task should be easy for Kagero and Narukami.
You can use his skill to call any Royal Paladin that's not Grade 3.
He can be 20000 if the whole field is full.
He can't be boosted.
The Counterblast 3 skill is kind of steep.

Artwork and aesthetics:
The card art is nice, kind of like Alfred showing he's the real boss. It really shows he's king.
9 out of 10, I say.
