implement basic turn cycle and projected "line"

[hitz]

For starters we will skip instants and combat - just need Draw + Main.
Draw obvious takes the top card off your deck and puts it in your hand.
Then system needs to project use of mana for the next M turns.

What is M?
Well what if we try M = number of planned turns + 1
A planned turn would be - examine Cards in Hand (CiH0 and project available mana to cast current CiH.
Let's say it's T2, I have 1 mountain in play, and a hand of 4 Bolts + Land. I can empty my hand by T3 no matter what I draw, so M = 2 (can plan for a T4 top deck). Obviously simplistic when everything costs 1. Can get trick when projecting future land draws.
