Guide to a Deck: Mirurun

Mirurun is an interesting deck. Mirurun's gimmick consists of utilizing her opponent's spells in the trash and at times from the hand/deck. Of course, her main focus isn't using the spells but the bonus effect she gets from using the spells. Overall on those regards, Mirurun makes a quite effective deck with the ability to banish SIGNIs quite easily and/or making her opponent discard their entire hand. However, due to the fact that she requires specific cards for her opponent to have in order to be useful, Mirurun can be classified as a hate deck, which is basically a deck meant to counter another deck specifically. In Mirurun's case, this specified deck is Piruluk, but she can also counter other Spell-heavy decks such as Hanayo 2-stop. On the other hand though, this also means that when she's fighting something that isn't Spell-heavy, or if the opponent plays smart and doesn't use any of his/her spells, she's next to useless.

Overall, Mirurun is very reliant on her opponent's cards to do what she does, but when she does it she does it decently well.

Overview

Okay, you know, I've been thinking but the Overview section seems sort of redundant considering how I just repeat everything I say up there in this section...

How the Deck Works 

Mirurun's main core is Beryllium. Beryllium is basically the only thing that makes Mirurun playable. Discarding one or Banishing one SIGNI is a considerably good effect already on it's own, and when you use two at once, the effect payoff is enough to leave a big enough scar in your opponent. I haven't even covered the synergy with Tico yet, which is even scarier considering that you can have 3 Beryllium at once on the field. Getting rid of Beryllium also poses drawbacks on your opponent, since you can discard your opponent's entire hand easily with 3 Beryllium if even one goes pop. That being said, though, only one Beryllium isn't exactly the scariest thing ever and won't do that much for you, and also uses up a lot of ener, so you may want to use her wisely. 

Aside from Beryllium lockdown though, Mirurun doesn't do much. Her entire deck's playstyle is focused around that. Other than that are just, well, good SIGNI I guess. Helium and Silicon help in drawing cards to help your advantages and make Beryllium consistent, while Sodium helps Silicon and Beryllium trigger. I would recommend Chlorine while I'm at it, but Chlorine and her Noble Gas friend mostly act only as filler which other stuff can arguably do better. Lithium is a good filler, and has a relatively good effect too. Uranium is a good SIGNI that can salvage cards, and Neon is a good alternative when you don't draw Beryllium.

Validity in the meta

I would give Mirurun a Tier B-. She's decent when she works, but has too many flaws to be considered higher than B- in my opinion. While the things Berylium can do are fairly destructive, that alone shouldn't be what makes a deck go running. Plus, she has no answer to a lot of decks in the meta that can annihilate it, namely Spinner decks.
