Blue Cloudpost versus Dimir Tempo Legacy

Let me gather all the necessary data simultaneously — resolving both archetypes and finding the relevant card.

Good — Dimir Tempo and Barrowgoyf resolved. Now let me try some likely names for Blue Cloudpost in Legacy:

I can see there's a "post" archetype (WBG) in Legacy. The user is asking about "Blue Cloudpost" which is a blue-heavy Cloudpost variant — but the only post archetype is WBG. Let me check for blue post variants and also run the matchup query with Barrowgoyf filter simultaneously.

I can see the "post" archetype is clearly Cloudpost. The ~14 decks with Islands and Force of Will/Force of Negation represent the "Blue Cloudpost" variant. Now let me run the matchup query filtering for entries with Barrowgoyf in the SB.

Something's off — 6 matches but 0 wins/losses/draws. Let me check the result field values and also investigate if the Barrowgoyf card_id needs verification against the sideboard data.

The result values are WIN, LOSS, DRAW — not W, L, D. Let me rerun the query with the correct values.

Now let me also register the alias and add context by checking how post with Barrowgoyf performs overall (not just vs Dimir Tempo), to give meaningful context.
