1 "Tenshi" Tuner + 1 or more non-Tuner monsters

1 Tuner + 1 or more non-Tuner "Tenshi" monsters
When this card is Synchro Summoned, inflict 300 damage to your opponent for every monster on the field. If this card attacks, you can flip the attack target face-down. If this card destroys a face-down defense position monster as a result of battle, inflict 500 damage to your opponent.

1 Tuner + "Tenshi of Dusk"
Once per turn, you can remove any number of "Tenshi" monsters in your hand. This turn, this card's maximum number of attacks becomes the number of cards removed by this effect. This card cannot be destroyed by Spells that don't target it.

1 Tuner + "Tenshi of the Dawn"
When this card battles an opponent's monster, the damage it inflicts is doubled and the monsters is destroyed after Damage Calculation. During battle between this attacking card and a Defense Position monster whose DEF is lower than the ATK of this card, inflict the difference as Battle Damage to your opponent. If this card destroys an opponents monster as a result of battle, you can remove it from play to increase the ATK of this card by 200.

Please provide suggestions, too!

I say lower the LP gain on Dawn's effect, maybey down to 300. If you limit it to your monsters though, 600 would be fine. Other effect seems fine.

Dusk's auto flip needs some kind of disadvantage, like mabey pay 300 LP or lower his ATK a little permanently every time he uses his effect.

For Sword of Night you need to tell where your cards are being removed to, though I'm assuming you meant to remove them from play. Seems a little UP'd to me, I'm thinking return them to the Deck instead, or you might want to just rework it.

Alright, I know Pride is kinda hard to summon, but I mean double all battle damage AND piercing?! That is too far. That and removing you're opponents monster from play to gain ATK, no real drawback there unless you're against a Macro Deck. Think up something new for that last effect and keep one of the first two effects, not both of them.

Now if it turns out your tuners are hard to bring out, it might be fine, but since I don't know any of them, I think some of them are OP'd.
