yu-gi-oh: I have a stand deck?!

Hey guys, so I've been working on what the effects of the new monsters and traps, so this is just a showcase of the first draft.

But I also came across a veeeery cute monster when I was out at vintage stock, it's called bunilla and I wish to have Jonah tame it via saving it from a corrupt duel spirit and make it the mascot.

And now… the new cards.

Cyborg- Rudol Von Stronheim

(earth-machine) (lvl4) (effect)

(Atk:1950 def:1500)

This card also counts as a warrior-type monster.

When this monster battles a monster with higher attack than itself, it gains 500 atk points and one level until the end of your turn.

Stone mask(ritual)- can only be used to ritual summon 'vampire' or 'pillar man' monsters, tribute monsters from your field or hand.

If your opponent has more monsters on the field than your own, you can use one of them as a tribute as well.

(Is this one spell too powerful?)

Stone of Aja (ritual)- can only be activated when 'stone mask' is in your gy, banish 'stone mask, stone of Aja and your pillar man monster to ritual summon an 'ultimate lifeform' monster from your extra deck.

You must tribute monsters from both sides of the field.

(Yes I'm making the ultimate lifeform-Kars a fusion/ritual monster, it's own unique monster, are you all fine with the idea?)

Pillar man-Kars (dark-zombie)(lvl7)(ritual)(effect)

(Atk:2800 def:2200)

Can only be ritual summoned by the 'stone mask' ritual spell

Cannot be destroyed by battle, if this card battles a light monster, this card loses 1000 atk until the end of the turn.

If this card deals battle damage to your opponent, you gain the damage as life points.

Pillar man-Esidisi (dark-spellcaster)(lvl6)(ritual)(effect)

(Atk:2000 def:2000)

Can only be ritual summoned by the 'stone mask' ritual spell.

When this card destroys an opponent's monster inflict 500 points of damage to your opponent.

(Yeah I don't know enough about Esidisi to give him an effect so feel free to give me a suggestion and I'll edit it at a later date.)

Pillar man-Wamuu (dark-warrior)(lvl7)(ritual)(effect)

(Atk:2600 def:2400)

This card is unaffected by card effects except it's own.

When this card battles an opponent's monster, you can sacrifice 400 life points, it gains 400 atk until the end of your opponent's turn.

Vampire-Straizo (dark-zombie)(lvl4)(effect)

(Def:1900 def:1900)

When this card inflicts damage to your opponent, you gain life points equal to the damage inflicted.

If this card attacks your opponent directly, its atk is halved until the end of the battle phase.

(Yeah while this guy is a vampire, I'm having the stone mask be for part 1 DIO, Jack the Ripper and the like.)

Nigurundayo!!(trap)- when your opponent attacks your monster(s) and it has higher atk, return one monster from your field to your hand, and end their turn.

When this card's effect resolves, search your deck for 'Hamon user-Joseph Joestar', add it to your hand.

Ultimate lifeform-Kars (divine-divine beast)(ritual)(fusion)(lvl12)(effect)

(Atk:3500 def:3500)

This card cannot be destroyed by battle or card effects.

When this card battles a monster with higher Atk, this card gains atk equal to the difference.

Anyways here's my first draft, let me know if I need to edit the cards provided and I'll see you all Thursday.
