Create-A-Card Competition

I don't usually enter these, but... what the hell.

Time Paradox
1010
Cast Spell
All entities are destroyed, including those in both player's hands.  Both graveyards are then added to their respective decks, and each player draws five new cards.  Mana totals of each player are now .
Failure: Skip your next three turns.


Unlock: Your opponent must skip ten turns in one game due to cards you control.  You must have a Cosmic Rift in play for every one of those turns, and still on the field when the game ends.  In addition, you do not unlock this card if you are made to skip even one turn by any card's effect.

Essentially, it resets everything but Lifepoints, Location and Obliterated cards.  Knowing my luck, I've probably forgotten something in it, though.

Big Red Button

Create Unique Device
Obliterate top half of your deck: Target entity is obliterated and Big Red Button is returned to your hand.
"The time has come... to push the button!"


Unlock: Win by Singularity Cannon with more than 300 attack when your opponent has no cards in their graveyard, all of your monster and effect slots are full, all entities on the field are Dark/Light and under your control, you have only one card in your hand and when precisely 75% of your deck is in your graveyard.
