MTG Salvation

Have some store credit on TCGPlayer and looking to make some last little tweaks to my Breya list:

Pretty happy with where the deck is but as always there's that feeling of wanting to improve it and whatnot.

Was wondering what people's experiences have been with Master Transmuter. It would be a very flavorful inclusion (based on lore, the card art literally depicts Breya) and the card itself has quite a bit of utility from being able to protect and/or put out combo pieces or other potential wincons to generating value out of Sol Ring or turning Duplicant into essentially "U: Exile target creature".

I just worry that it may be a touch slow and/or draw removal before actually managing to do anything with it.

Depends on your meta. It worked well in my Sydri, Galvanic Genius deck, but my group isn’t very combo oriented. If your group is really competitive it will be too slow for you; anything less and it’s a solid addition.
