I'm here another time for asking something about Jokers ruling. If the Jokers Civilization is treated as colorless, why the people in this video are making mistakes?

• At 2:38 the player on the right tap Fujiyaman and Bullman Churis in mana to summon Vorg.

• At 4:39 the player on the left tap Fujiyaman, Bullman Churis, Ifrit and Vorg to summon Vorg and then Bullman.

How is this possible? Is this a misake or not?
