So full disclosure, I've been playing some magnetic mech decks, and I am a fan. After lots of play-testing, I do think it needs some kind of tweak. It seems to me the idea of merging two minions together should have some permanency. I don't think the stat merging should be silence-able (deathrattle, lifesteal, other effects should go when you silence) or break it into two silenced versions of the original mechs. Second, when you bounce a minion that has been magnetized back to the hand, it should retain the stats/abilities of the two minions.
I'm sure many of you will disagree, but I'm looking for constructive dialogue about this idea. Thanks.
I personally think magnetic is more thematically appropriate than fuse. There is almost nothing that would make sense fusing. Oozes maybe. It is perfectly fine to have keywords contained to a single set. Recruit was contained to one set, echo is probably contained to one set. Magnetic should be no different. You can get a little crazier with expansion keywords than base set keywords too. Aside from that, I am completely in favor of giving each tribe their own unique mechanic. Mechs and murlocs are kind of boring in that way. Dragons have hand mechanics, elementals have played the turn before mechanic. I think having something like that for each tribe makes each tribe cooler.
The way they handled magnetic tells me they are not planning to using it outside of the set. Which is fine, it makes them have to come up with the next cool mechanic.
I would not assume magnetic will be a this set only key word. I know we have not had a "if an elemental was played the turn before" card since ungoro, but the hand mechanic part of dragons shows up in most sets. I expect to see future elementals with the if u played an elemental mechanic. I also like that mechs get magnetic. There were a number of "if u have a mech in play" cards in gvg and magnetic sticks with that theme. It just seems flavorful and interesting making magnetic a generic keyword dosent feel quite as good and u would have to tone down the power level to prevent major abuse
We haven't had adapt since Ungoro. Or echo since witchwood. Overkill will likely be RR only. I think we're just getting single expansion keywords.
