Yeah, this ability made sense in MH1 with cycling... outside of Opt I've yet to see a single card that would make this "second card" mechanic viable in limited in any way.
I love Mantle of Tides. Good 1 drop, remembers me of Delver of Secrets
I like they are pushing the limited second card draw matters archetypes. But in MH1 it was one of the worst archetypes, the only really good payoff was the Djinn card, the commons were mediocre. This set has more "second draw" cards, but it has less card draw options to activate the effects (MH1 had cycling, fact or fiction, a bunch of stuff). It will probably end up as another failed attempt I think.
In common so far we have Tome Raider, Witching Well (the best ones imo), Merchant of the Vale, Opt and Golden Egg
