[Koko Daily Challenge! 001/100] Heavenly dragon, here my cry!

[Althemia]

2 or more Level 5 LIGHT monsters
This card can also by Xyz Summoned by using a Rank 4 LIGHT Xyz Monster you control with only LIGHT monster(s) as it's Xyz Materials. (Xyz Materials attached to that monster also become Xyz Materials on this card.) If you do, this card cannot activate it's effects during this turn. While this card has 3 or more Xyz Materials, it cannot be destroyed by your opponent's card effects. Once per turn: You can detach 1 Xyz Material from this card; destroy all cards your opponent controls in the same column as this card.

Yeah I keep wanting to get back into card making but I never seem to get myself motivated. So I decided that I'd take a look through my CFV folder and post a card every day with artwork I like from there. So yeaaaaah.

Next time on Koko's Daily Challenge! "Dragons of the heaven, surpass your limits to deliver the thunderous end!"

So, even with only two Xyz Materials, this thing's a Rank 5 3k beatstick with no drawbacks...  Since Level 5 LIGHT monsters are easy to bring out (Cyber Dragon, Solar Jammer, Constellars, and so on), summoning this monster is actually quite easy.  And that doesn't even count the effect it gets when it has three Xyz Materials...  That is easily done in the first turn with a Constellar deck with only two Level fours in your hand and a Constellar Xyz Monster in your Extra Deck...  Needless to say, this thing is quite overpowered.  Perhaps you can prevent it from direct attacks like with ZW - Leo Arms or something?
