As I don't get it, what 4/5 that don't start in your deck are you referring to?
You get a spell from Primordial Glyph, for example Flamestrike, that spell don't start in your deck, because of Glyph the spell cost 5, if you play this card the cost will be reduced for 3.
Edit:
Goodbye Water Elemental? This could fit into some sort of Quest Mage / Elemental package / Highlader Deck. Or all 3? Solid card.
So works with Servant of Kalimos and probably Pyros 2nd and 3rd forms in elemental mage too...
This is straight busted. It's going to be so annoying to play against this.
Bonkers card. Great ability and premium stats, will see a lot of play.
"forum has bad, unrealistic opinions" the card
Why does this have good stats, tribal synergy, and powerful mana reduction effect? This is just stupid.
More tools for combo mage.
ugh. like ethereal peddler, but totally broken instead of extremely gimmicky.
The next question is, effected on the greater spellstones? Cause them are not in the Deck to begin of the game.
And Malchezar makes sense too.
Brace yourselves, for Prince Malchezaar Mage is upon us.
All realities, all dimensions, are open to him. In this one, you lose.
(In all seriousness, broken card. Works magic in Elemental Mage.)

Oh man...
x2 in all mages decks except Highlander.
Finally you can discount spells from Mana Bind.
