Just a thread that seems like a good idea. I see there is one member missing from combiners maybe a event where you can collect all the members and then at the end of the event you get a devastator/bruticus/other combiner card if you have all the members.
I suspect that Devastator and/or Bruticus would be their own card, and likely a 4 at that, as that would just be the easiest way to do it... BUT I would love to see if you filled a complete set of Combaticons/Constructicons that they would merge at the start of the battle. Granted, would a bunch of 2s and 3s (I think one of the Combaticons is a three) make a worthy addition to your team or would you be so handicapped it wouldn't ever make sense to use them? Anyhow, it would seem to be the most likely event... And, unfortunately, I cannot really think of anything. (I would like to see my campaign missions added.
Considering the amount of combiner team members in the game I was suprised that there were no actual gestalts. So yeah some thing using them would be good. But I'd prefer a permanent expansion rather than timed event. If they wanted to make it really tough maybe you would have to have all the team members scanned and max level before you unlock the gestalt by merging there cards. Or maybe the combined form is a separate card that gets a extra bonus if you merge a team member with it? There's also the Dinobots. Just do the same as the Insecticon event but with Grimlocks gang instead and special versions of select Decepticon cards. Not to mention all the later G1 stuff they could add like Head/Target/Power/Action masters, Pretenders, the later Japanese stuff, Cybertron versions of cards and other worlds to boot.
Combiners is a no-brainer. I'd like to see Targetmasters as weapon cards. Adding other sub-groups would be nice to see, not just combiners. A Dinobots event would be cool. So far we only have Predacons, Combaticons, and Constructicons, let's see Stunticons and Autobot combiners.
Wreck n Rule: a good excuse to get a Whirl card. Also, where the heck are the Triple Changers? They would Trans-scan just like any other card, except the altmode card would have 2 vehicles on it- They would all be level 3 and up
Triple changers could have three cards, one for each mode. Having to get all three to scan them could be offset by higher stats than other cards of the same rarity.
Unicron would be great but he would be the rarest card in the game most likely Im going with everyone else I would like to see a dinobot event but I think it would be interesting if they added event missions where you can find the event cards ending with a boss battle unlocking one of the rarer cards.
