Why don't you want a Fangblade too? He's an officer, of course, but I think he's a very strong card. As I heard somewhere, there's a good saying about him: "even when you're trading, you still punch in the face."

Yes, he's pretty cool, but I have enough expensive cards among the commanders. Besides, all sorts of Leons shoot from a cannon with a range of 9. If I add Fangblade, it would only be at the expense of cheaper units like angels and thieves, but I doubt that wouldn't critically affect early survivability. Unless I only add one...

And, probably, you can add more Unicorns and Healing Angels if you're going for a control strategy. Or, on the contrary, throw them out and just sit behind a Ward.

Why is that better than the current combination? I'm unlikely to survive the early rounds with just healing, there are limited options for Swords in this regard, and Wards aren't a panacea either... It's actually good to put a Ward and a Unicorn on the field at the same time and watch the opponent try to get rid of the latter as quickly as possible with uncertain success.

Roland is a great card in the arena, but I can't imagine him in ranked. Rarely anyone deals a lot of damage, and if they do, it means you've been doing something wrong for a long time and lost control of the field. Unless it's against some De-shifts, it might work...

Lunablood will be top-tier, but they haven't really caught on.

Lunablood is actually very strong, at least at my rank, they compete with Serpents.

I doubt the usefulness of Luminous Knight, he's much more useful when summoned by a Mage, and he's not great as a 2-cost unit on his own, he dies from Mei or a Sniper or a Missile or anything, unless he gets a Cannon upgrade in the late game.

First, the Cannon, yes. Second, the Knight works well with a Mage because when you have a Mage on the field, you can never have too many Knights – constantly evolve them and reap the rewards. And he's the only 2-cost commander who can do something in a non-officer deck.

I also have a lot of doubts about the usefulness of Roger, as a 6-cost unit, Alvida is better, he has slightly worse stats, but at least his effect is consistent.

3 damage to the face for 6 is, of course, "super value," considering that I questioned the usefulness of newbies who deal 2 for 3. And as a Ward at that stage, Alvida is also not great.

You can also try Geno, he's a commander, and his rush can easily save the day, and add Knights for enhancement, so there's someone to buff.

No, Geno is an officer. Otherwise, I would have added him anyway; he would be no worse than Gawain. Okay, I'll think about what can be done here. Thank you for the comments.
