This card is treated as a Normal Monster while face-up on the field or in the Graveyard. While this card is face-up on the field, you can Normal Summon it to have it be treated as an Effect Monster with this effect:● Once per turn, you can place 1 Spell Counter on a face-up card on the field that you can place a Spell Counter on. If you do, this card gains 600 ATK until the End Phase.
Dark Valkyria is a perfect pair to Crusader of Endymion. Crusader of Endymion generate Spell Counters for Dark Valkyria to use as attack boost or targeting removal. Additionally both of them benefit from Spellcaster and Gemini Support.
Magical Citadel of Endymion might be the best place to dump all your Spell counters. Card effects that use Spell Counters can fuel their cost from Spell Counters attached to Magical Citadel of Endymion. Additionally Magical Citadel of Endymion can protect itself with its own Spell counters.
Here are some cards you can put Spell Counters on.
So, are they giving us this card for real? that's pretty cool, I've noticed geminis are quite a popular archetype right now thanks to Gemini Spark (even if it requires lots of URs to be competitive). Quite an attractive deck and fairly competitive, good to see it's receiving support.
There’s a great combo between this and Dark Valkyria passing Spell Counters, Destroying Cards, and boosting attack once both are Gemini’s, the only question is how quickly can we make this happen to be viable?
