Enchanted creature can't attack or block.

Simple Pacifism variant. Surprisingly, it doesn't seem to have been printed yet.
I think the reason effects along these lines haven't been printed yet is that if your opponent sacrifices or protects their creature in response to the aura, you don't get the soldiers either, which is a major feelbad.

If I was going to design a card along these lines, I'd do it like this:


Under Watch - 2WW
Enchantment - Uncommon

When ~ enters the battlefield, create two 1/1 white Soldier creature tokens.

When ~ enters the battlefield, exile target creature an opponent controls until ~ leaves the battlefield.

At the beginning of your upkeep, if you control no creatures, sacrifice ~.
