 Except that have a low cost spell in a big spell deck balance itself.

What you do if critical mass is the last in your deck and  if you have two in the combo can fail since critical mass is also a spell.

Draw variance and the fact that itself has low cost makes it a meme at best.

While that dragoncalling is just our normal powerlevel. Yeah i'm got that people not like things that cheat over mana cost but on turn 10 it is reasonable enough.

Sorry to say but you have no idea on what a balanced card is.

What determines which cards are selected? No offense but quite a few of these have mistakes/are overpowered....

Perparations

Dragoncalling deserves to be a legendary! In other words is like saying summon a 5/5 dragon and cast a pyroblast (plus the fact you gives +2 to Dragoncaller Alanna ), plus the fact is also good to run in a tempo aggro mage.

Yeah, but keep in mind that's possible only at 10 mana. Similar like Kun, the forgotten king, except he is good standalone.

Love parroting, but that has the potential to be so ridiculously broken (assuming the 1/1 parrot costs 1)

I'm voting for Seek because I think that it's actually both balanced and a card that would see print by Blizzard.  In addition, it's got superb utility and would be great in a lot of Rogue decks.

Parroting is definitely sweet and I could see it being a thing.  As could The Lone Hunt.  Fence's Trade and Yogg's Blessing are both kinda meh.  Time Is Money, Friend and Critical Mass are both busted AF. 

Seek is a great fanmade card, but in practice is really busted. It's a targeted draw for one mana in a class that, since release, has been about drawing your deck (miracle rogue)

2 Critical Mass + 2 pyroblast + 2 Frostbolt, hope that you draw both critical masses and frostbolts before you draw both pyroblast, win

The real definitive Exodia Mage xD

Fence's trade with echo cards is great. And it also good by itself

"Time is money, friend!" is op as hell in wild, i like 

Parroting has the best flavour.

The parrot is awesome. Nice card design

It seems like time and time again people don't value drawing a card enough... As a rule of thumb, it's worth 1.5 mana, which makes any 1 cost card that says "draw a card" too powerful unless the text is a disadvantage. Don't even get me started on 0 mana draw a card ones.

Yeah, it costs 1,5 mana, but using a card in itself is worth 1 Mana.

1 mana "draw a card" wouldn't see play in any deck, that doesn't have any sort of spell synergy.

Considering Flare used to be in each and every Hunter deck when it cost 1 mana and more often than not did nothing, I beg to differ.

There are two things to consider here.

First of all, we're talking about a time, where only the Classic and Basic cards were out, generally making options weaker in general.

Second of all, a 1 Mana Flare, that never did anything would NEVER be played in a Hunter deck nowadays. Tracking basically makes you choose one of three cards, and are only seen in some versions of Hunter decks. A 1 mana draw a card with a very slight upside is not a problem.

That's easy - in Rogue, it's strictly better. In every deck that wants specific cards, it's strictly better. Now, considering those two, and adding an EASILY MANIPULATED tutor effect? Every rogue deck would start by putting those cards and then deciding on a win condition, and that's the epitome of OP. There are a good number of cards I would trade for it in the current miracle rogue, which is already a world championship deck. It's simply too powerful not to play, and thus, too powerful, period.

Using a cycle card when you're looking for specific cards is always good, you just have to see the decks running novice engineer (that costs 2!) to realize that. True, right now it's mainly big spell mage, but there were a lot of other decks through the years, and there will be more in the future. Unless, of course, you put that card, and then all Rogues would run it instead (or in addition to, at least)
