He is amazingly good imo. His first lets you both draw an extra card for 4 loyalty (not bad) it also lets you pick between the first 3 (amazing). Also, whichever ones you don’t select can be snagged reliably by his 2nd later in the game. Once you get going you are sifting through 4+ cards a turn. That is unbelievably strong.
His third is one of the better skills in the game and yet I rarely play it. But a 12/12 prevent damage that digs out supports every turn… wowzers.
I actually think he has THE BEST skillsets in the game (yes, NB and Kiora.. including you). His only downfall in color locked nodes is his access to cards basically turns him into a mono-walker. And you are usually better off going with a dual.
If the way bolas was released is any indication, they’ll probably offer karn again for cash , but at a higher price. Obviously I’m just guessing, but it seems like something that could happen again.
I don’t think they will find much people to buy it this time. The ones that didn’t bought it earlier are either awaiting for a crystal purchase or short of runes.
Besides, who would pay twice the initial price without feeling ripped off …
