4 Eak Q: If I have a Balance and one other card in my hand and use Lion's Eye Diamond to cast Balance, will Balance treat my hand as though it has one card or zero cards?

A: You can't use Lion's Eye Diamond to cast a spell from your hand. You can only play the Diamond's ability when you could play an instant. When the ability resolves (immediately, because it is a mana ability) you have to discard your hand.

because of this statement I can Affirm that LED doesn´t help to get a first turn win which is what we intend to do with the deck Ritgfh? , I agree is good with I.Tutor and with burning and with mystical tutor but can't give us mana in first turn to cast A.N therefore if we are suposed when we play A.N we will win we really don't mind which cards will be drawn . Simple .

what about the Retract /Hurkills effect + Permanent_Artifacts_which_give_more_mana_than_its_cost synergy ?
Do you really think the Í.T + LED is the quieckest way?
do you really think LED helps to our 1st turn win?
