The first time i played magic i was a twelve year old, i bought a couple of packs and immediately some middle age people at the lgs tried to look at what i got, i ended up being forced to trade my exalted angel for a llanowar elf. I mean forced because there was a lot of social pressure around me. I played with some friends for a while but then left the game a couple years later (i never went back to the lgs). Today I'm a grown up and retook magic since dominaria and i try to collect as much of the game as I can, I sometimes wonder if i over collect due to how unsavoury the game was back then. But I've started to feel it's unsustainable, there's so much going on and getting released that I'm not enjoying collecting so many cards. How do you recommend someone transitions into a bit more of a casual player that doesn't feel they need to get every card. I don't want to stop playing as i love the game, i want to enjoy it as much as I have three last few years.

There is a lot of gradient between collect nothing and collect everything. Something a lot of players do is pick a category of things that they feel would be fun to collect (a certain creature type, a certain artist, a certain category of effect, etc.) and just collect that.

Is WotC going to update the Oracle ruling for cards like Exalted Angel who, though having a keyword's name, don't have it in their text boxes?

Exalted Angel is not going to get errataed to have Exalted.

now that KTK's been revealed in its entirety, am i right in saying that there are no reprinted morphers? was there ever any talk of reprinting, say, exalted angel/grinning demon/blistering firecat?

We did consider some morph reprints. None ended up making the cut.
