Best side board character in the game with monoma. As for the sideboard essentially you don’t have to show your character until after they’ve sided. I’ve already played an event where this came up and that’s how they ruled it. So your opponent doesn’t get to have the information until after they’ve sided and shuffled.
I also think togas attack is bomb in shigaraki as it doesn’t say it can’t reduce your opponent less than 1. Comboing it with keen observation, or even exploding pride together could threaten lethal not to mention off the back of shigarakis response.
