If they go too far with Eudora and turn it into a meta player you are about to have a Kazakusan meta. I’m pretty sure nobody wants that. Making it 5 is fine but taking it to 4 would be a REALLY bad idea.
If they gave a (1) mana discount the card would probably be very playable. More than (1) would probably make it a must play and possibly create a high tempo DH deck just off playing it. Kind of like how Buttons is when played.
Overall it’s interesting that they are taking a different route for once and giving mass buffs and not nerfs. I am guessing this is some kind of experiment since it’s not something we normally expect.
That’s fine but then we need to go back and do the same with previous sets and take back a bunch of unnecessary nerfs that were handed out to legendary cards previously.
