Shadowverse

one of the worst options

A decent option. Not the best, of course, but preferable to the current leaders.
It's a shame that the elves ended up with a mediocre princess instead of Aerin. Instead of a good leader, they got something that's barely better than Arissa, leaving Selvin as the best leader in his archetype.
The knights, runes, and Haven have good options; I might even take some of them.
The dragons have a so-so, average option. But it's better than Rovan, anyway. Somewhere on the level of Forte.
But the Shadowcraft got the worst leader in the game, even though there were some decent candidates. I'd rather play as leaders from Street Fighter than this abomination.

And it's a shame about Roland, of course. The best card in its archetype and the best candidate for a leader, but it didn't make the cut. =
