Lyna's Light

A Lyna/Hijiri/banish deck with Synchros and Xyzs.

Spoiler:

I was told I should post it, so I did.

for starters

-3 horn of the unicorn

+3 practically anything else

I don't like how The Agent of Mystery - Earth only has one target; maybe you can try teching in The Agent of Creation - Venus and Mystical Shine Balls as well, since it also gives you access to Herald of Pure Light. I also am not sure why you have Maiden with Blue Eyes, but no Blue-Eyes itself... I would think it's kind of useless in that respect. Perhaps try something like Effect Veiler instead.

Also you have a lot of backrow hate, but not much monster protection... considering you run a LOT of monsters in this deck, I'd consider dropping a few of them (or maybe those Horn of Unicorns) to add some staple traps like Bottomless, Compulsory, D-Prison, etc., just to help with field presence. Also you should add a Foolish Burial to help with consistency.

Not a bad deck otherwise. There are some cool things in here, and I will say that the side deck is very clever
What's the first card in the very top left, btw?

White Potan

No, I meant top LEFT, not top right

its Rainbow Kuriboh
