Everyone uses draw effects from time to time. Or if they don't, they toolbox, searching for a card from their deck and adding it straight to their hand.
However, this challenge is all about getting cards to hand. I'm not going to pick what you use it for - Slifer, Exodia, do what you will, but at least one half of your deck must focus on getting cards from deck to hand.
Yes, cards such as Gold Sarcophagus, which add the card after X turns, do qualify for this assignment.
Card Destruction is off the banned list, you can run at least one (1) copy if you want.
Keep in mind that you do not want to deck out.
Note how I did not say whose hand the cards would go to or from whose deck. Have fun with this! It's great for trolling!
I would like to see the decklist, even if you don't use a ton of cards, to verify what you have. You can have as many copies as you like, within the rules. No 35 Upstart Goblins people.
