Hm, on balance, I think trading will not break the game, and may stoke more interest in it.

Optimus, there may be some moderate loss to Mobage revenues if trading is allowed, since people will push less hard during an event if they know complacently that they can trade for the other half afterwards. However, this may be offset by the increased interest in the game if trading IS allowed and more people play (and pay) to collect'em all. Currently there is no way to be a collector in this game, since you're outta luck if the miss getting a particular card.

The Grimlock flood problem - the sudden spike in MTM R5s - may be an issue, but not a  game-breakingly big one. There will be more MTM R5s in existence, but they will be highly diffused throughout the TFL population. If you look at the Ravage thread and assume those unlucky sods with only rav bots or only rav alts traded, it would still be their 1st or 2nd R5 for most of these players. That's not a huge upgrade in power level. Instead of 100 decks running around with 9x R5s and 50,000 decks with only T2, now you have 50,000 decks with possibly 1 or at most 2 MTM R5s in there. That's not too horrible, power-inflation wise.

In raids, even full R5 decks are helpless on Day 1 - you hear T1 players complain that their base decks of awesome R5s are quickly replaced by 9x raids. So a flood of Grimlocks still won't make raids a walk in the park, people must still get raids (still making Mobage money).

In campaigns, more MTMed R5s in decks means more decks can farm the Hard levels, so mobage may have to make the levels harder or compensate in other ways. Or they can just not make any correction since the players will be competing for the top 100 scores still and it's all just relative anyway.

In PVPs, more R5s in decks means even T1 or quasi-T1 decks will face black knights with only a couple of R5s but still risky contenders. T1 players may, out of fear of losing, choose to toss in an extra cube just so the R5 in the underdog's deck doesn't help score an unlikely win over them. This profits Mobage so it won't be gamebreaking.
