When you summon this card, you totally control the game unless your opponent has any light cards in his deck.
Personally, I would try to summon this creature as fast as possible making sure the game is under control. Then, I would go straight for the shields.
Strategies and game play:
I would put this deck in a nature light deck. Nature focuses on mana acceleration while light will focus on evolving into alphadios .
Combos with other cards:
A card good is dorballom. Although it is hard to put both cards in the same deck, if you could, it will be really powerful. I would first summon dorballom and wipe out his mana and creatures the i would summon alphadios to keep everything safe from your opponent's spells and creatures.
Ways to counteract it:
The only way I know of counteract is the card Apocalypse day
when you summon this creature, you almost win the game.
Not many. Only way to destroy this creature is light destruction spells which are very little.
It is only printed in Japanese.
Artwork and aesthetics:
The picture is pretty awesome!!!
