I'm not entirely happy with the flavour of Rearguard in that last post. Let's fix that.
Eternal Guardian Creature - Spirit Soldier
Indestructible, defender
~ can't block alone.

Such was their love for the holy man, Ahrai's guards whisked him away from danger at the battle of Kazal. If they were so eager to protect, he declared, they would atone by doing so ever more.Sworn Protector Creature - Human Warrior

And while we're at it, let's do a few new cards too.
Noble Steed Creature - Horse
T: Target Soldier or Warrior becomes a knight, gets +2/+2 and gains first strike until end of turn.
2/2
A prerequisite for knighthood.Ghost Lathe Artifact
At the beginning of your end step, put a Soul counter on ~ for each enchantment you control. Then, if you control no enchantments, sacrifice ~ and create a 1/1 white Spirit creature token for each Soul counter on ~.
-I'm tempted to put this at
. Maybe if they didn't have flying.
Computational Loop At the beginning of your end step, put a charge counter on ~ for each artifact you control. Then, if you control no artifacts, sacrifice ~ and gain life equal to the number of charge counters on ~.
-I'm tempted to make these transform back and forth into each other.
Mind Body And Spirit Enchantment
At the beginning of your end step, gain 1 life if you cast an instant or sorcery spell this turn, then do the same for creature and enchantment spells.
Then, if you gained 3 or more life this way, draw two cards.
-Would it be more interesting mechanically if it just wanted you to cast X types of spells? It would get a reflavour of course, and unless the cmc went way up, wouldn't gain you life.
