Historic Refresh
Historic really needs some life breathed into it. With all the cards available I see so many of these three:
1) Kor Spiritdancer/Sram/Lurrus
2) Minion of the Mighty
3) Muxus, Goblin Grandee
Don't get me wrong, I love it when people find cool combos, but these are just done to death (like run the stats if you can). You could really reopen historic up by removing Kor and Minion (even if temporarily) so we get the brains churning again. These are historic unranked best of ones - my quick pick. Best of three has a much longer wait time and ranked has more variety, but I think all levels should offer a wide array.
And I totally get I could just make cheap spot removal decks, but doing it to avoid a turn two loss seems more of a game mechanic issue and less play style in my opinion.
And Muxus. Have always loved the goblins, but he could use a rework to make his ability more in tune. Like if you control three or more other goblins then he brings the boys in. Just entering means only counters are going to stop him and with up to eight lords that can supply haste (and then be sac'd for another Mux if you have another in hand) is a bit overpowered in my opinion. Threats should have an adequate response window.
Thanks for the consideration!
