@Serracollector But realistically this list of cards that don't help Thorn/Gush directly that might actually be considered taken off are:
Imp Seal / Vampiric / Mystical
Lion's Eye Diamond / Lotus Petal
The problem is pretty much everyone of these cards helps combo, which then potentially makes Thorns that much better. Maybe turning things into more of a 3 horse, instead of a 2 horse race is better though. I don't know.
Much smaller sample, but the opinion poll here seems pretty much the same as the facebook group one:
13/22 want Mentor Restricted, and 1 more maybe.
15/22 people checked some sort of change, but only 12/22 actually asked for change specifically.
6 want Gush Restricted, and 3 more maybes. That's 9 total, which is the same number that explicitly checked No change.
@vaughnbros Restrict every card. One of everything!
I will say that highlander is a really fun format to play. I loved it when my friends and I played it before cube became popular (though to be honest, not a lot of difference between highlander and powered cube).
Highlander is less skill intensive I think (aside from deckbuilding) than Vintage, but such a deep card pool. Only issue I had was the lack of 4 wastelands makes LIbrary of Alexandria a little ridiculous.
If you're looking for a fun night, give it a try. Love the format!
