A Fantastic Dreamer

The Lady that Traveled Across the Dreams
*6 Spellcaster/Effect Light 0/0
When this card is summoned, banish all cards in your graveyard. Thrice per duel, when a Spell/Trap effect is activated or if this card would be destroyed, you can banish this card and special summon 1 monster banished by this card. Return it to the banished pile during your next end phase and special summon this card from the banished pile. During each of your end phase, banish 4 cards from the top of your deck. When this card is sent to the graveyard or banished other than by its own effect, return all cards from your banished pile to your graveyard.

The Woman that Stayed in a Dream
*8 Spellcaster/Effect Light 0/0
Cannot be normal summoned or set. Can only be special summoned in ATK position if you have 14 cards or more in your graveyard OR if you have 10 cards or more in your banished pile. When this card is summoned, banish all monster from your deck. This card cannot be destroyed by battle or by card effects and it's battle position cannot be changed. Once per turn, special summon 1 of your banished monsters. During your end phase, return 4 monster cards from your banished pile to your deck.

Nice concept in the first one. It's like an amazing toolbox. I might just have to make a deck around it

Second one makes a good combo with the first. Powerful together, but you run out of targets with this one or mill yourself with the other, so I guess it's OK.
