isnt this only good though if you can cheat it out ?

since to play this and a spell would take 10 mana. why not just play the spell ?

is the only real benifit is that you  technically get a 5/5 attached to your spell ? but its still at the cost of two cards.

i dont see this card realistically living to your next turn in many cases. also other then pyroblast, are there even any cards worth playing along with this ?

 This is a battlecry, so it doesn't need to live.  In mage decks that run pyroblast, you are often fighting for board until you can finish with it.  This will allow you to play it on five and make your swing turns bigger and when the time comes your turn 10 could potentially could be double pyroblast.

This is a battlecry so it sets the cost to 5; Kalecgos is a stagnant ability, so your first spell will still cost 0.
