As always, I request the judgment of the experts here on Multiverse to help me determine if I've worded this card correctly.

This wording seems to broadly work, though I suspect it'd be more likely to be worded "Whenever you would draw a card for the first time in a turn".

Problems I can see are that it's a bit good with Future Sight, Mul Daya Channelers etc - although it's only "draw an extra card per turn" good anyway so that's probably fine - and, more problematically, that it causes a shuffle every turn. Remember that in tournaments shuffling takes 2-3 minutes, and the Rebels mechanic (Ramosian Sergeant and friends) was problematic precisely because it caused a shuffle every turn.

WHAT!? Who in their right mind would take 2 - 3 minutes to shuffle a deck? That's crazy! The longest I've ever seen anyone take to shuffle a deck is about 30 seconds and I usually do it in 5 - 10 seconds. What are they doing that takes that long? If someone did that to me more than once in a game at a major tournament, I might start thinking about calling a judge over and complaining about delay of game.

Anyway, I'm aware of the interactions with cards that make you play with the top card of your library revealed, (Oracle of Mul Daya included) but that just means you need two cards to pull that off. It's not a guarantee, but perhaps to help balance it I should make the casting cost ?

As for the way I worded it, I modeled that after the Miracle mechanic on cards like Banishing Stroke but I see you went in the direction of cards like Kira, Great Glass-Spinner. So I'll make some changes and tell me what you think.

Given that you can get "draw an extra card a turn" for with upside on Honden of Seeing Winds, and this requires either a combo or great guessing skills to be that, I think was fine. I imagine it might be fine for in fact.

The wording looks good to me now, except for a glitch that I totally didn't spot last time - it should be "If you would", not "Whenever you would". "Whenever" is for triggered abilities but "would... instead" is for replacement abilities.

Shuffling in a tournament means a full pile shuffle that actually randomises pretty well. Shuffling every turn is crazy. But you could probably just say "Reveal a random card from your deck"? I don't think anything has ever done it before; but it seems a natural enough operation.

That'd imply a shuffle, which would imply the full 2 minute shuffle in tournaments too.

How about name a card and reveal the top X cards from your library. If the named card is revealed put into hand & draw a card,. Ten put rest on bottom in any order ?

I was presuming cut and take without shuffle afterwards being the physical implementation of reveal a random. Take it, and maybe draw an extra one would seem to avoid the whole problem.

How about, "If you would draw a card, if it’s the first card you would draw this turn, instead name a card. Then reveal a card at random from your library. If it’s the named card, put it into your hand and draw a card. Otherwise, put the revealed card into your hand."

When dealing with random cards in hand, you'd just let your opponent pick a card randomly out of your hand, right? I don't see how that would imply a shuffle if the same concept was applied to a whole deck.

I'm just glad that at TCG tournaments here in Japan players only pile shuffle at the start of a match. In game, you just give your deck a few quick mixes, offer to your opponent to cut and it's over in about 15 seconds. If someone tried to do a full pile shuffle on me in the middle of a tournament I'd feel I had the right to punch them in the face for being a dick and wasting time.

Yep, I think you can count yourself lucky you weren't trying to play tournaments during the Mercadian Masques era then.

For a number of reasons, y'know, starting with the annoying coinflip of who gets their Lin Sivvi out first, going on through how awful Prophecy was, and maybe hitting the shuffling issue somewhere towards the bottom :)
