Looking for any constructive criticism on this deck because I really like Heraldics so I want to make this deck as consistent as possible.

Deck List: https://i.imgur.com/UhVaWGy.png

Amphisbaena (the OCG heraldic beast) usually is summoned by the discard effect so the normal summon of the turn isnt taken up. But sometimes my hand is depleted a lot due to xyz summon plays.So usually i'm only left with 2 heraldic beast monsters in hand. So unless the other heraldic beast is leo, i cant xyz symmon that turn. So kagetokage is better in that situation. I find it very rare to get kagetokage dead in hand since i always have at least 1 other heraldic beast in hand.

Thanks. I look forward to that.

I'd probably switch horn of heaven out for lance....
But that's preference (Since HOrn of heaven is so dumb that it can't stop fusions, rituals, basically any card that is summoned some other way #TeamSolemnWarning)
Your build is pretty consistent looking. If you want to utilize more search power and your grave more you may wanna use the field spell and unicorn. I hated unicorn till the new guy came out. BUt meh mine wasn't too competitive (Even though it was decent) .

Also, why all the Shaddoll hate in your Side deck?

I might try out Unicore, but he's really only worth running at 1 because you really only need the heraldic ocg xyz once to set up your plays.  And yeah the black horn of heaven should be taken out.  The field spell searches for your spell heraldic cards but you can only summon heraldic beasts or psychic type xyz monsters, which is only useful if you want to summon heraldic beast monsters but it's pretty dead when you want to do something to your opponent on that turn. Sure it helps for your next turn but your opponent might do something crazy next turn. The meta decks these days.  And for the Shaddoll hate, Construct and Winda are like the worst things Heraldics can go against.  Construct to get rid of your xyzs and winda to stop your plays.

Yeah I've seen other builds of heraldics, some with the tcg and some that use the ocg cards. I like their builds and incorporated some of their card choices into mine, like 2 fiendish and 2 breakthrough or photon thrasher. But I also saw some builds i didn't really like, like 3 of the heraldic field spell card and some of the other heraldic beast cards, like heraldry charge or eale. And i tested a lot with the deck. Lately i tried 1 unicorn and seems fine to me. I don't like the field spell since even though you can set up your plays for next turn, you can only summon heraldic beast or psychic xyz monsters that turn, and I only run 3 psychic type xyz monsters. And in today's meta, decks are really fast and can set up a field on the next turn.
