Randomly popping up Extra Deck monsters format

[Mysty]

This format makes sure you aren't too reliant on your Extra Deck monsters, since they will not always be accessible.

Rules:

• You must use a 15 card Extra Deck this format. No exceptions.

• After counting the Extra Decks and Main Decks to make sure they are within legal parameters and drawing 5 cards from your Main Deck, Extra Deck monsters are shuffled into the Main Deck. If an Extra Deck monster would be returned to the Deck or Main Deck, it gets returned to the Main Deck instead. (Do note they are now eligible to be returned to the Main Deck as costs.) If it gets returned to the "hand" or "Extra Deck", they still go to the Extra Deck instead.

• Immediately before you draw any card, look at the top card of your deck, and if it is an Extra Deck monster, you are honor-bound to put it into your Extra Deck and repeat this process until a card that isn't an Extra Deck monster is on top. You do not have to show the opponent any card you draw, but two things help make sure you don't cheat:
- Extra Deck monsters are relatively useless in the hand, so you will want to return them anyway. Also, if you ever use an Extra Deck monster in your hand for any purpose, you lose the Duel.
- At the end of the duel, both player's reveal the cards in their Extra Deck. If either player has a card in there that doesn't belong in the extra Deck, they lose. If both players do, the game is a draw and both players are despicable cheaters.
Note that this rule doesn't apply to non-drawing effects. If your Extra Deck monster gets milled, it gets milled.

• To help with access of the Extra deck monsters, the Standby Phase gets something relevant to do. Immediately at the beginning of the Standby Phase, before anyone can chain anything, if there is at least 1 Extra Deck monster in your Main Deck, reveal cards from the top of your Deck until you hit an Extra Deck monster. Put that card into your Extra Deck and shuffle your Deck. This only happens once each Standby Phase. Use information about your field, Graveyard, and Extra Deck size to derive if there are any left in your Deck.

• As you probably guessed, you can't "properly summon" an Extra Deck monster if it isn't in the Extra Deck. That's the part that makes it 'randomly popping up'.

Yes, I know this format is horrid in the same way Lightsworns are a horrid archetype design. But so is Team Duels with randomly-assigned teams, and my locals still finds it fun (except for the occasional times that the Chaos Dragons player gets stuck with the Gravekeeper's player. But now the Chaos Dragons player now runs Mermail-Atlantean.dek, so it's all fine now). I have yet to test this out, but I imagine this could probably be a blast with decks that don't rely all too much on their Extra Deck.

EDIT: Slight edit to the rules due to people summoning their Extra deck monsters. now you only do the Extra Deck reveal procedure if they are any in the Main Deck

EDIT 2: You draw your 5 cards before shuffling in the Extra Deck monsters. Don't want some people starting off with a natural lead.

Sounds interesting, though there is a problem I have with the Standby Phase rules. Cards that add to the top of the Deck are gonna be useless, but is that just the way it's gonna be? I like the rest though.

Correct, this basically doesn't change the situation for bouncing cards to the top of the deck, unless you put an Extra Deck card to the top of their Deck and mill it within the same turn (which is highly unlikely based on how few people run mill of any kind). I don't plan on changing that either, since putting a card on top of a deck is somewhat like returning it to the hand with a "skip a draw" attached.

EDIT: I might have misunderstood your question. Also, adjusted a rule just to make sure you don't reveal your entire deck unsuccessfully.

Hm alright, while that's not a choice I would have made, so be it. I sadly can't try this ATM, as I can only play online (my area doesn't have any place to play at all), that they don't really allow you to do that.

So what do you suggest? I'm open to whatever suggestions. This was after all, an idea I thought up in less than 5 minutes and typed up.
