No. The Wave 2 Combiner Dinobots must be used. This was covered in avideo.
One cargo trailer 🠪 +1 attack
Two cargo trailers 🠪 +4 attack
Three cargo trailers 🠪 +9 attack
Each cargo trailer checks for how many cargo trailers are on the bot. So, with three cargo trailers equipped, the first one checks, sees that three cargo trailers are on the bot, and adds three attack. Then the second one checks and adds an additional three attack and so on.
This is based on a Facebook screenshot shared on Discord of a question WotC answered
Bumblebee - Electrum Warrior
Alt-mode: "When you flip to this mode -> This character has Bold 2 until end of turn. "
Bot-mode: "While this character has 5 or more damage counters -> It has Tough 2. "
Yes, zero is a pile. It is perfectly fine to split the cards into two piles, one of four cards and one of zero. Listen to thisdesigner interview for confirmation (30:26 into the interview).
It scraps at the end of your current turn and is not present for your second turn.
You can't bring back a Body mode character from KO because it won't have a head. Effects like I Still Function! and Involuntary Promotion will not work at all to bring back a Body. You can, however, bring back a Head from KO because it will be in Bot mode (and only in Bot mode).
Ruling from a lost WotC article
No. You may use any 4 star or less Head mode character.
Yes, Tidal Wave does combine. WotC (Drew) confirmed this in a comment to thiscommunity poll.
In the 1985Changing Gears episode of the G1 cartoon, Gears has a circuit removed and becomes a happy to please mechanoid who will help anyone, including the Decepticons. The symbol on the stratagem isstated to be a tongue in cheek reference to that episode.
No. It is solely for Autobot Springer - Aerial Defense. The lack of "Autobot" in the stratagem target is believed to be unintended.
Toolbox only adds 1 to the total being repaired. The 'for each' in Versatility is looping to calculate the amount of repair that will be done, then the repair is applied as one event. Raider Ratbat works the same way.
Wave 1's Chop Shop however works the other way. It has the repair inside the for each, allowing Toolbox to apply for each repaired damage.
