Lyonar is definitely one of the most straight-forward factions. Even the Alabaster Titan archetype doesn’t seem too different from standard tempo lists, just a more clear win con and the obvious lack of a few key spells.
My fear for pushing Lyonar to a lategame faction is that in order to do so, you need strong removal, and Lyonar’s removal is definitely not the greatest. This worries me because IF Lyonar got stronger removal, they would also have the heavily-statted minions to pair with that removal.
Lyonar is never too far from the top of the tier list, and that’s because it’s hard to go wrong with minions that have large stats. More removal could push Lyonar to a level I don’t want to imagine.
If the faction is going to see change, I hope it’s in the form of a keyword ability. Zeal seems so boring. Gaining a few stats when close to your general? I’m not amused if I’m being honest. As of now though, healing decks are the only ones I can see as lategame decks.
