Welcome to ????????

The Start of Illusion
Spell Card
Add 1 "The Sacred Land of Illusion" from your graveyard or deck. Then, if you control no monsters, banish 1 card on the field and in your hand.
"Once, a goddess awakened in a strange land. A beautiful place, where magic is in the air, and the residents live in harmony. A beautiful illusion that lures the goddess like a flower lures a bee."

The Sacred Land of Illusion
Continuous Spell Card
If you control a monster, this card is treated as a field spell card and is moved to the field spell zone. If this card is in the Spell/Trap zone, this card cannot be removed from the field. Once per turn during either player's turn, you can banish 1 monster you control. If you do, during the end phase, special summon it back to your side of the field, then draw 1 card. If this card is in the Field Spell zone, once per turn you can banish 1 level or lower monster from your deck or graveyard. If you do, during your end phase, banish 1 card in your hand then special summon it to your side of the field.
"A land, concealed from the world to protect the magic inside it. Its residents called it a paradise, but in reality it's only an illusion"

The Promised Illusion
Quick-play spell card
Add 1 of your banished monster to the hand. If you control a "The Sacred Land of Illusion", special summon it to your side of the field. You can only activate 1 "The Promised Illusion" per turn.
"Magical creatures from all over the world pursued the same illusion, an illusion of a sanctuary to save them from the ever changing world."

Living in an Illusion
Continuous Spell Card
All monsters you control with "banish" in its card text gains 500 ATK. Once per turn, you can tribute 1 monster with "banish" in its card text you control to reveal the top 5 cards of your deck. If you control a face-up "The Sacred Land Of Illusion", add one of them to your hand, otherwise shuffle the cards to your deck then draw 1 card.
There lives many wonderful creatures in the land of illusion. All of them is trapped in the beautiful illusion."

End of Illusion
Counter Trap Card
Activate only if you control a face-up "The Sacred Land of Illusion". Negate the effect of a spell/trap card or the summon of a monster then banish it. If you do, send a "The Sacred Land of illusion from your side of the field to the graveyard, ignoring its effect.
During your end phase, if you have no face-up cards on the field, activate 1 "The Sacred Land of Illusion" from your graveyard or deck.
"In the end though, an illusion is still an illusion, the beautiful world is as fragile as a glass. But as the illusion of the land collapses, a new illusion is created somewhere else..."

This makes me wish we could have flavor text for our cards. Are yours from anything specific or are all of them made from you?

somewhat based from a game, actually.

but yeah, flavor texts is awesome.

You and your Touhou

a biiit of touhou, since the field is basically gensokyo.

otherwise, not so much.
