You can manage & track your card collection and decks once you create an account and login.
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.
In this scenario, you would be able to add Espionage back to your hand.
Quick answer: Yes, and yes.
Not so quick answer: Each Crash Landing is triggered separately.
It’s possible you might be looking at an older iteration of the FAQ. There were conflicting answers earlier in the set’s life, but Steamroll’s damage carryover is not considered attack damage.
Playing more than one instance of Steamroll on the same character has no additional effect. The extra damage will carry over only once.
2. No. As you noted, the character with Grenade Launcher did not attack.
In this scenario, Air Raid’s ability can’t do anything because Sunstorm has been KO’d and as a result, his upgrades have been scrapped. Crash Landing’s effect will work.
There aren’t official rules for this, but we recommended letting the loser of the first game choosing who goes first in the next game.
1. At the end of the battle, you can swap one card in your hand for a green battle icon card you’ve flipped.
2. It does not trigger Shockwave’s ability because you’re not scrapping a card from your hand. The flipped cards are being scrapped.
