Guide to a Deck: Iona

Iona is waifu for many people, making her preety popular. Aside from being waifu material, Iona is a decent deck to use. Her level 5, Ultima/Maiden, is the best lockdown button the game had ever offered us, limiting your field to only 1 SIGNI and letting you only draw once per turn, it's preety easy to out-resource your opponent as well as making them unable to do anything. It just completely and throughly kills off Resona decks, makes Hanare's purpose of living poof away, and helps in nerfing Ulith's Enigma Aura even harder than it already is. Plus, if you're fighting against Eldora or other decks that uses card comboes as their main playstyle, Ultima can make their lives miserable using that "Can only draw one card per turn" clause, making their comboes, while maybe not impossible if you trash over them, limited since you can run out of resources preety easily in this matchup. While all these problems apply to you too, you have Dark Matter and Quinn to work with, unlike your opponent, which can make a world's difference.

Guide to a Deck: Hanare

During her first release, Iona was given the German Poison Fangs and Labyrinth as her "unique" SIGNI class for her to work with. The idea seemed to revolve around using Labyrinths for defense and utility while using Poison Fangs for the offense, namely using Violence Splash and Vier=Rikabuto. Well, they also gave Iona Vimana and Rikabuto was proven to be unreliable preety quickly while Ultima became a thing, so Rikabuto died out preety easily, and Poison Fangs, without a place to go to, lost their place (a friend of mine did use the Hanare formula to make Poison Fang Iona mildly decent again, but that's another story since no one else did that) and, with the exception of a few of them, was never seen in the metagame again. Ever.

Or so TakaraTomy made you think and gave you Hanare.

Hanare, for the most part, was made to pick up Iona's leftovers in the form of Poison Fangs, and when she was first announced a lot, and I mean a lot of people got hyped. This included me, since I always liked the concept of Venom. And to live up to that hype, TakaraTomy gave Hanare a ton of support. A ton. If this amount of support went to... Tama, I would have probably raided TakaraTomy for it. In this case though, it went to a new LRIG type that didn't have much and that everyone was hyped for, so no one complained nor could complain.

Guide to a Deck: Ulith

Ulith is a potent deck. Having access to some of the best cards for defence, and having a vast option for gaining resource and chipping in damage, Ulith's main way of winning is outgrinding your opponent. Using cards such as Enigma Aura, Ulith can easily bring herself out of the lethal zone, since any form of field removal won't help in doing extra damage, as well as having multiple low-costed or free ways to defend herself, making killing an Ulith deck with the ideal setup extremely hard.

Due to all of these low-costed ways of defending herself and utility she has access to, Ulith stood and still stands as one of the best anti-meta decks in the game, being able to counter the key strategies of quite a number of decks. To name a few, there is Midoriko/Mel with their Retribution, Hanayo who has a limited amount of Attack Phase banishes, and so on.

Guide to a Deck: Alfou

Alfou is a good deck. While she is restricted to level 2 for all of her stuff, the things that she can do with just a level 2 is vast. Alike to many other 2-stop decks, Alfou's bane is rushing. Alfou does this well, combining Sayuragi's On-Play effect to banish things from early on, while also crushing additional Life Cloth indirectly by milling her opponent out. She can also mill herself out to use Bride of Usurpation to do an Attack Phase banish with Sayuragi, and being Black, has access to quality salvages. Finally, Alfou milling out her opponent can lock APEX and the likes down.

Overall, Alfou is a good rush deck that can pressure your opponent throughout the entire game, while being able to crush 4 Life Cloth in a turn.

Guide to a Deck: Myuu

Flap... fap?

Myuu, the resona girl, is a hyper offensive deck that can easily kill your opponent by field wiping them with Ougusoku, Nanahoshi, and Heike, while also doing Assassinations with Vespers and On-Attack banishes with Scarab to refuse your opponent ener if they use ARTS. Of course, this is after Charming all of them with Tsukutsuku, Minmin and Tamamushi. Myuu has it's fair share of defense too. Kumamusu is an amazing and annoying card that works fantastically, especially with Imago's Ener Charging skill negating the cost, and that same Imago provides you a lot of ener to use in ARTS. Myuu also has preety damned good defensive ARTS, such as Four Color Miasma,
Bloody Slash, Charm Tactics combined with Ougusoku and Nanahoshi. Myuu has a lack of reliable finisher, but she doesn't really need any, considering just how offensive she is regardless. Overall, Myuu is a great deck in the metagame, while also being one of the three Resona LRIGs actually seeing anything close to "play" in the metagame for a reason.

Guide to a Deck: Tama

THIGHS

Tama is a great deck. Being the main character's deck, this might have been obvious though. At one point, Tama was the only deck that topped, and nothing else. This was thanks to Arcgain, who was, and still is, one of the best ARTS blocker to exist. Combining this with Tama's offensive potential, it doesn't take a lot of thinking to realize how Tama became the best deck. Over the years however, Arcgain got banned to two, and Piruluk Lambda came, providing Piruluk decks with an extremely reliable way to deal with Arcgain. That was followed by the likes of Storm Warming, Tawil-5, 4CM, APEX, and other sorts of cards that can bypass Arcgain's effect, hugely decreasing the effectiveness of Arcgain over the years. That being said, Tama is still a considerably potent deck even now, since Arcgain is still extremely effective, and a bunch of other cards restricted to Tama are decently good. Overall, Tama is, at minimum, above average compared to other decks, but below average when compared to the top of the meta, but still somewhat good. Tama also makes a mildly decent deck for giving to a beginner, since it holds all of the game's basic foundations while not being completely busted.
