Oh yeah, I totally missed him, sorry.

Yes, today.
That’s not my favorite matchup but I try to get as much heal cards as I can and then try to get a board advantage without getting my hp too low.
Another thing that wins me a lot of games vs secret mages is to try to proc duplicate on kabal lackey or arcanologist.
If they have secrets in hand to play for free with the 2 duplicate’s lackey is fine, they wont have too much cards in their hand. If they want to play the 2 duplicate’s arcanologist they have to spend a lot of mana to get secrets in play, and a 2/3+secret on turn 5 should be fine.
My suggestion is that if you find a lot of secret mages and other aggro decks just cut the vulpera and leeroy out and put something more defensive like ziliax and tar creeper.
Unfortunately there are no anti secrets techs for odd 🙁
