Sparky won't let you play Alchemy decks using Haywire Mite
I have Alchemy decks that use Haywire Mite. I can't play that deck in a Bot Match unless I first change the format of the deck to "Direct Challenge" or Historic. When I do that, it changes the Mite to a 1/1 creature, which is fine. It's a pain in the neck to have to change decks just to try it out in a Bot Match.
This appears to be a recent change, perhaps with the recent Ixalan release.
