I found Doomsday vs Show and Tell data, but "Sneak and Show" and "Reanimator" returned no matches as separate archetypes. Let me check which combo/spread archetypes are actually in the Legacy database and get their matchup data.
Now I can see the relevant archetypes. Let me get Doomsday's matchups vs the key combo/spread decks.
