But at the same time, units within the thunder prison's range would be randomly struck by lightning, which had a chance of inflicting paralysis on its targets.]

Aside from the basic +2,000 boosts to Magic Attack and Magic Defense and the +2 rank increase, the additional effects possessed by [Underworld God] of [Osiris's Nether Thunder Dragon] were entirely different from those of [Underworld God] of [Osiris's Black Spirit Vulture].
First, [Underworld God] granted [Osiris's Nether Thunder Dragon] complete immunity to Electric Type Ultimate Moves and gave it the field skill—[Thunder Prison].
Judging from its description, [Thunder Prison] was an exceptionally domineering Electric Type field.
Any unit within the range of [Thunder Prison], friend or foe alike, would be attacked by lightning.
Thus, this [Osiris's Nether Thunder Dragon] broadly suited two types of decks.
One was a specialized [Graveyard] deck that needed to "suicide" to fill the graveyard.
The other was a more conventional [Electric Type] deck, though it would need to include a large number of Magic Spirit Cards with Electric Type immunity.
Dark had few Magitech Cards that could work with it, but he did have one.
That was right—the likewise [God Card], [Thundurus]!
And judging by their effects, [Thundurus] and [Thunder Prison] were practically a perfect match!
With these two [God Cards] as support, he might be able to put together a fairly decent Electric Type deck without much difficulty.

[Osiris's Nether Thunder Dragon]'s second Ultimate Move was [Nether Thunder Bolt].
Judging by the name, it seemed like an Ultimate Move meant to replace Dragon Breath... and it appeared to possess both Dark and Electric Type attributes.
