Retrains of Y-Dragon Head and Z-Metal Tank

[DifferentDimensionVanessa]

Y-Dragon Coil

Machine / Union / E.

This card's name is treated as "Y-Dragon Head" on the field.

Once per turn, you can either: Target 1 LIGHT-Machine monster you control; equip this card to that target, OR: Unequip this card and Special Summon it. A monster equipped with this card gains 400 ATK/DEF and cannot be targeted by monster effects. If the equipped monster would be destroyed by battle or card effect, you can destroy this card instead. When this card is sent to the GY, you can target one monster on the field; make its ATK 0.

If you control "X-Head Cannon" or "Z-Metal Tank", you can discard this card; place one "XYZ Combine" from your Deck onto your Spell/Trap Zone.

[ATK 1600]

[DEF 1500]

 

Z-Metal Irrigator

Machine / Union / E.

This card's name is treated as "Z-Metal Tank" on the field.

Once per turn, you can either: Target 1 LIGHT-Machine monster you control; equip this card to that target, OR: Unequip this card and Special Summon it. A monster equipped with this card gains 600 ATK/DEF and cannot be targeted by monster effects. If the equipped monster would be destroyed by battle or card effect. When this card is sent to the GY, you can banish 1 card in your opponent's hand.

If you control "X-Head Cannon" or "Y-Dragon Head", you can discard this card; place one "XYZ Hyper Cannon" from your Deck onto your Spell/Trap Zone.

In the anime, one or both of Yugi and Kaiba call the XYZ monsters "Magnet" monsters in the beginning. Y-Dragon Coil is a Coil because the number of coils in electromagnetism gives the magnetic field strength.

Irrigator is here because Z-Metal Tank's original name is Z-Metal Caterpillar. Caterpillar tunnels require irrigation and caterpillars may benefit somewhat from it. The non-stop disruption to ecosystems and plants today made me name the card in consideration of it.

You didn't make the last one X-head Cannon ?

Mixed feelings towards the banish-from-hand effect of Z-Tank because on one hand, it has no OPT clause whatsoever do if you can mill multiples or loop them, it could kill the entire hand of the opponent as soon as in Turn 1. Yet on the other hand, it is a "when... you can" effect, which means it can miss the timing, so you got to be careful with your chains when sending it to the GY.

The rest seems fine, not problematic, but I do not think they would be too great for the XYZ archetype.
