In Duels, Loyal Sidekick is not properly gaining stats if copied with Ancient Reflections. Here is a screenshot of them staying as 1/1s:

For comparison, here is Butch, a very similarly worded card, gaining his stats properly when reflected:

Ancient Reflections summons 1/1 copies, which is taking your buffed minion and summon a 1/1 version of it
I’m aware, but that is an aura buff, so it should still be applying to the 1/1s. It does so for Butch, who also has an aura buff.
Just lost a game because of this one… I gave my opponent’s 12/12 a divine shield, just to summon a 1/1 copy of it…
