Discard phase and hand size

Xakarath

I'm interested in having a magic style discard and cleanup step.

Turn order would look like this:
Start
Draw
Main (move spells, activate planeswalker)
Match
Cast
Attack
"Discard."
End

Discard would allow us a chance to discard down to the appropriate hand size without missing draws. I would advise not to allow changing the hand order, however, due to how mana drain strategies work.

Hand size can be handled few ways. One is to please increase it to "max size down to 7" for all. Not allowing draws because we hit our max hand size is un-magic like.

Another way would be to flavor it to the planeswalker. Since the "tough" walkers have more life, make the smart walkers able to have larger hands. +1 hand size ~= +10-20 start life

Thanks for any consideration.
