In general, when it comes to Magic Arena budget decks, I try to keep the total number of rares and mythics to under 15, which, for Mono-Black Persist, meant we had room under the budget to play Castle Locthwain and still come in at just 13 total rares and mythics
That means no targeted removal, no board wipes, and no headaches
Since it might not be on Mega Dream EX because the base Charizard Y is for the start decks 100 The last Start Deck 100 had a special deck that was composed of secret rares (including the 3 gold Galarian birds)
I enjoy resolving everything from Archon of Cruelty, to Etali, to a melded Brisela and Im guessing you do too
