Taeboch, God of Councils

At the beginning of your upkeep, if your combined devotion to White, Blue and Black is more than 10, put a colourless 1/2 spirit council creature token into play.
If you control an even number of spirit council creatures, spells your opponents cast cost {1} more to cast.
If you control an odd number of spirit council creatures, opponents cannot play spells during your turn.
