Oh by the way, I've got some scans that I was waiting to drop since I didn't want to swarm you guys with just single card reveals.
Here's Inferno:

This guy is a tank. He hits so hard, and he defends so much, that this guy is frankly idiotic to try to take down. You'd think that the best thing about him is his ability -- and you would be wrong. It's about every other little detail about this guy added up to make a formidable tank. With three base defense, this guy blocks most damage that he is dealt. Being Ranged, he can also make use of the Rapid Assault Armor Battle Card, giving him four defense and disrupting your opponent. He also has a base eight attack, which is one of the highest in the game along with the newly revealed Optimus Prime. But even more than that, with such a high defense, you can heal off the majority of damage you take with Team Up Tactics thanks to the fact that he is a Truck.
In fact, I built Shockwave / Inferno just last night and playtested it against Cars, which I thought would be an autowin. But I was wrong. The problem is this: His ability to return cards to your opponent's hand sounds great in theory, but when your opponent plays Turbo Boosters to untap their characters to attack you ad infinitum, you really don't want to put those cards back into your opponent's hand.
It's also a tall build, meaning you only have to characters to attack with, putting you at an even bigger disadvantage to Cars. You just end up losing because you attack a total of three times in a game. You can't even take advantage of Ready For Action. Shockwave as a partner is just not cutting it.
But on his own? Inferno can really bring the pain. Just imagine him with someone to supplement his healing, using their smaller attacks to set up knockouts before finishing them off with a huge attack from Inferno. The only problem is finding someone to fit that bill. Great potential, bad partners for the moment.

This isn't a character, but I like the picture of Bombshell playing with himself.
But anyway, to my thoughts.
This card is really, really good. Forget about the card being scrapped from your opponent's hand -- if they've been playing the game at all, they can afford it -- but the upgrade being scrapped and a card being drawn for you? That's fantastic.
But here's the thing. The reason why I'm so excited about this isn't that your opponent is punished for knocking out a bug on your side -- why I'm so excited is that you can use this
on your turn. You can pop this thing with Skrapnel's insect mode, which knocks out one of your Insecticons to forcefully tap one of your opponent's characters. Meaning, you can choose a target and lock your opponent out of an attack with that character at the same time. But with this, though, you even get to disrupt your opponent and draw a card while you're at it.
Es wunderbar, ja?
