Head’s up, I spoke to the team about this!
Summon: Uses the Summoner’s Magic stat to determine the level.
Transform: When a troop transforms itself into another troop, it keeps its existing level.
In your instance @awryan, the first copycat is the summoned one, and the second copycat on the opponent’s team is the doppelganger which has transformed, keeping its pre-existing level. If I have misinterpreted your screenshots, please let me know.
