Let's say you have a team of combiners. And your opponent’s characters are all tapped out. You have one character untapped and all of your characters are in bot mode. I know you can’t use Inferno Breath in this instance because you wouldn’t be able to attack to end the turn. However, if you play Brainstorm and then play Inferno Breath, tapping your last character and then using the Brainstorm’s second effect to play and enigma and combine, is that a legal play?

In this scenario, you actually could play Inferno Breath because you can tap your last character. When it comes time to attack, if you have no untapped characters, your turn would end. If your opponent also has no untapped character, you would untap all characters as usual and your opponent’s turn would begin. If you play the enigma and combine your characters into a Combiner, the Combiner begins untapped, so it would be the character that attacks.
