Citizens of the Spark Solo Play - Attractive or Scyntilla-ting

About Citizens of the Spark, from BoardGameGeek:

The fate of creatures touched by the spark of intelligence hangs in the balance. You must recruit strong animal allies to your city and unlock the potential of your citizens if your settlement is to survive the days to come. Citizens of the Spark is a variable set-up card game in which players take turns attracting citizens, taking actions, and claiming sparks. The more citizen cards a player has of a specific type, the more powerful that citizen's action becomes. The player with the most sparks in their city when the deck runs out wins! Play with 7-10 animal citizen types per game, chosen from 30 available creatures and combined into one shared deck. Every citizen type has distinct powers, making each game's action combos uniquely variable. On your turn, recruit multiple citizens by selecting an available group of cards, placing them in your city tableau, and grouping like citizens together to grow their action strength. Next, select one type of citizen in your tableau to activate, taking the effect of the card and discarding it from your city. But keep watch on rival cities, because when you activate a citizen, all players can follow your move and activate a matching citizen of their own!
