Splinterlands: My Legendary Frontier Cards Ranking

Hello Splinterlands Summoners! The Frontier mode has been live for quite some time. It's the free to play version of Splinterlands where players can earn Frontier set cards. While some of these cards are not that great compared to others, there are some decent ones that can be used in the Modern mode. In this post, I'll be ranking the legendary cards based on their utility as I see it.
The Legendary Frontier Units

There are seven legendary cards including two that can be acquired from the missions. However, the legendary cards are not created equal. Some are stronger and have more utility than others. Maybe a couple or three of these legendary units can even be useful in the Modern or Wild modes of the game. On the other hand, there are units that in my opinion can be used only in some specific situations.
I'll be ranking the units from least to most useful in my opinion. Feel free to comment if you agree or disagree with my assessment.
Rank D: A'lan Musketeer and Agniavan Salamander


Both these units are eight mana ranged attackers. Musketeer deals two ranged damage and has the Double Strike ability while the Salamander deals one ranged damage and has the Blast ability. Both look impressive as damage dealers because of their abilities. I have the Musketeer but because of his high mana, I rarely use him in the Frontier mode. I suspect that the case will be the same if I have the Salamander. Also, I would find less use with them in the Modern Format where there are a lot of cards that can take up the slots in battle.
Rank C: Great Bear Druid

The Great Bear Druid is one of the units I frequently use in the Frontier. In high mana battles, he's great as a secondary tank because of his dual attack of magic and melee. He also has a decent health pool that is good enough for tank duties. On the other hand, he doesn't have any ability which was the reason he was ranked so low.
Rank B: Giam Root and Celestial Guardian


I ranked these two units together but one could be better than the other. Giam Root deals two ranged damage and has eleven health. He also has the Strengthen ability making him useful in rulesets where health is important like Noxious Fumes. Because of his high health, he can play tank in some situations or in Close Range rulesets.
Celestial Guardian deals two magic damage and has the Flying ability. He's a good damage dealer in the Frontier and decent in Modern. Plus, he's useful in Earthquake rulesets where there are not much flying units in the Frontier.
Rank A: Little Sister

Little Sister can be obtained from the missions which is why she is undervalued. Looking at her stats and abilities, she's one of the top and can be used even in Modern mode. She deals two magic damage and has two abilities. She has Life Leech and Flying abilities making her useful in Noxious Fumes and Earthquake rulesets.
Rank S: Mystic Scaleweaver

Mystic Scaleweaver is no doubt the best in this group as evidenced by her price in the market. She deals three magic damage and has the Slow ability. This is a great combo of stats and ability for a Frontier card that made her a sought after card. This also caused the archon to be in demand and I often see them played in the Modern mode. I'm frustrated to lose to this combo of magic teams.
Here's one battle where my Modern team was beaten by a magic team led by the Frontier archon and Mystic Scaleweaver. It makes me consider to buy and level up may magic archon to three and use her in the Modern Format.

The enemy team cut through mine like hot knife on butter. Their damage is just so great my team couldn't keep up.
Final Thoughts
That completes my rankings. These are based on my judgement and how I'll find use for the cards. I'd like to hear your thoughts on your own rankings of the reward cards.
I only need one more copy to level up Little Sister to two and while I don't like to buy Frontier cards, I'm considering buying one to speed up the process. Mystic Scaleweaver, Giam Root and Celestial Guardian are also on my list of desired cards. I would like to grind and be excited to get them from chests so I'm avoiding buying them even if their price is low.
