I have found griffin witchers unplayable with the current interface. I play on a mobile device, pc’s might be different.
First there is not enough time to remember what the cards do, check the board situation, choose cards to shuffle in and out of hand and to play the cards without without making errors due to a slow interface.
Then, half the time I have to check a box without any indication what the box does (eg discard a card, play a card, etc).
Half the time when I do tap a box, nothing happens; the other half, when I tap a box, it is so laggy that I think nothing happened.
Finally targeting also often doesn’t work. Rather than target, I get a red arch indicating an illegal target. I tap the card and target and nothing happens. Often I try three or four times to make it work. Normally that is livable— except when I am cut short on time because of fighting the interface on other actions.
I have played four games with a griffon witcher deck. On every one, I made at least one interface based misplay. So I am abandoning this archetype for something less frustrating.
