You do take a cut from sales right? That should be enough of a deterrent from people trying abuse high level cards that cost a fair amount.

Yes, agree for high level or maxed cards it makes absolutely no sense to take the 5% fee and with low level cards you can't climb the ladder of the leaderboard, but may get the daily boosters. I think of the role of a neutral market buyer who now can get a pig in a poke if such card is currently in cooldown. He don't cares about history of the seller, he just wanna get some working cards for battle.

While gifting a card with recent battle history should be in cooldown to prevent acc rotation because there is no 5% fee and risk of losing a card to another buyer or in other words punishment, but selling on the market, i don't see the reason for most cases. If someone is doing that, he pays high fees for a small chance to beat the Top10 which is ever changing or to get one booster a day for daily 5% or more fee, makes no sense at all in my eyes. The cut also goes to Steem Monsters, so no worries about because someone who tries that will pay more fees than he will get back.. at least in most cases i think.

I like the the more decision based gameplay of the future in terms of more fun and excitement to play, great and hope to see a better ranking point system without exaggeration like now.
