Zeus, Poseidon, Hades

[William79]

Here is my first three cards made in Yu-Gi-Oh! Card Maker!

 

[spoiler='Olympian Jupiter Zeus']
2 Level 8 LIGHT monsters
Must be Xyz Summoned and cannot be Special Summoned by other ways. Once per turn, during your Main Phase, you can activate 1 of these effects:
- Detach 1 Xyz Material from this card to negate the effects of all face-up cards on the field, except this card, until the End Phase.
- While this card has no Xyz Materials, you can target 1 face-up monster your opponent controls, then send the top 3 cards of your Deck to the Graveyard. If a LIGHT monster is sent to the Graveyard by this effect, attach the target monster to this card as Xyz Material. If not, your opponent draws 1 card and gains 1000 Life Points.

[spoiler='Olympian Neptune Poseidon']

2 Level 8 WATER monsters

Must be Xyz Summoned and cannot be Special Summoned by other ways. Once per turn, during your Main Phase, you can activate 1 of these effects:

- Detach 1 Xyz Material from this card to shuffle all face-up monsters on the field into their owner's Deck, except this card.

- While this card has no Xyz Materials, you can target 1 face-up monster your opponent controls, then send the top 3 cards of your Deck to the Graveyard. If a WATER monster is sent to the Graveyard by this effect, attach the target monster to this card as Xyz Material. If not, your opponent draws 1 card and gains 1000 Life Points.

[/spoiler]

 

[spoiler='Olympian Pluto Hades']

2 Level 8 DARK monsters

Must be Xyz Summoned and cannot be Special Summoned by other ways. Once per turn, during your Main Phase, you can activate 1 of these effects:

- Detach 1 Xyz Material from this card to shuffle all Spell and Trap Cards on the field into their owner's Deck.

- While this card has no Xyz Materials, you can target 1 face-up monster your opponent controls, then send the top 3 cards of your Deck to the Graveyard. If a DARK monster is sent to the Graveyard by this effect, attach the target monster to this card as Xyz Material. If not, your opponent draws 1 card and gains 1000 Life Points.

[/spoiler]

[goddamnit names are a pain]

The only flaw I see is that Poseidon is hugely broken. Mermails could tweak and summon, and his effect would set up merciless OTKs.

[Lucas the Flame]

All of these cards have the same last effect that seems to be a bit op, run an attribute deck that can get one out and you get to remove one of your opponents monsters and you get a free material.
