Custom Archetype - Ainu

[Zanarkand]

Hey all. This is my first time posting a thread on this site so I figured I'd kick it off with a full archetype that I've been working on. I haven't drawn any art for the cards yet since I've just been focusing on working out the kinks in the effects. Other than that, some feedback on how to make the archetype better would be greatly appreciated.
 
Here they are:

 
When this card is normal summoned, you can special summon 1 "Ainu" monster from your hand, except "Ellam, Crow of the Ainu".
If this card is special summoned, you can send 2 "Ainu" monsters from your extra deck to your graveyard; special summon 1 level 4 "Ainu" monster from your graveyard, except "Ellam, Crow of the Ainu". You cannot special summon monsters, except "Ainu" monsters during the turn you activated either of these effects.


 
If you have an "Ainu" Xyz monster in your graveyard, you can special summon this card from your hand, then shuffle all Xyz monsters in your graveyard into the extra deck, but you can only summon "Ainu" monsters for the rest of the turn. If this card attacks a defense position monster, inflict piercing damage to your opponent.
 

 
When this card is normal summoned, you can send 1 "Ainu" monster from your extra deck to the graveyard; add 1 "Ainu" spell/trap card from your graveyard to your hand.
If this card is special summoned, you can shuffle all Xyz monsters from your graveyard into the extra deck; add 1 "Ainu" monster from your graveyard to your hand


 
You can send 1 "Ainu" monster from your extra deck to the graveyard; add 1 "Ainu" card from your deck to your hand. You can only use this effect of "Vihnu, Raptor of the Ainu" once per turn.
When this card is special summoned, you can shuffle all Xyz monsters in your graveyard into the extra deck; destroy 1 spell or trap card on the field.


 
Each time an "Ainu" monster(s) is sent to your graveyard, place 1 Feathercoat counter on this card (Max. 3). You can remove 3 Feathercoat counters from this card to target 1 "Ainu" monster in your graveyard; special summon it.


 
Equip only to an "Ainu" monster. The equipped monster gains 400 ATK and DEF and cannot be destroyed by your opponent's card (either by battle or effect). If there is an "Ainu" Xyz monster in your graveyard, you can send this face-up card and 1 "Ainu" monster from your extra deck to the graveyard; shuffle all Xyz monsters in your graveyard into the deck, then special summon 1 "Ainu" monster from your deck.


 
2 level 4 "Ainu" monsters
Cannot be destroyed by battle. You can detach 2 Xyz materials from this card; draw 1 card. While this card has no Xyz material, you opponent cannot target monsters you control for attacks or effects, except this one. During the next end phase after this card was sent to the graveyard: return it to the extra deck, then reduce the ATK of all monsters your opponent currently controls by 500x the amount of monsters you control.


 
2 level 4 "Ainu" monsters
You can detach 2 Xyz materials from this card; draw 1 card. While this card has no Xyz material, neither player can add more than 1 card from their deck and/or graveyard to their hand per turn. During the next end phase after this card was sent to the graveyard: return it to the extra deck, then return 1 face-down card your opponent controls to the hand.


 
2 level 4 "Ainu" monsters
You can detach 2 Xyz materials from this card; draw 1 card. If this card battles a special summoned monster while it has no Xyz material, destroy that monster at the start of the damage step. During the next end phase after this card was sent to the graveyard, return it to the extra deck, then inflict 1000 damage to your opponent.


 
3 level 4 "Ainu" monsters
You can detach 3 Xyz materials from this card; draw 2 cards. Once per turn, during either player's turn while this card has no Xyz material, you can target 1 face-up card on the field; negate its effects until the end phase. During the next end phase after this card was sent to the graveyard, return it to the extra deck, then add 1 "Ainu" spell/trap card from your deck to your hand.

 
 
As you can see the basic idea behind it is that the maindeck monsters use the extra deck monsters as cost for effects, and then the extra deck monsters get mild additional effects from being used for those costs.
My little lore I made for it is that this is a tribe of birds who pay tribute to their ancestors, and in turn those ancestors grant them miracles. Not a very deep lore but I thought it was cool enough.
