Thank you so much for the responses!
First of all, thanks Rose, some of the cards you suggested are really good.
Silkguard for 1 green mana to cast is actually a way to protect. I did not know
Spectral Steel, and it looks like it should work wonders, actually found a copy of it in the card collection
With Halvar, I actually forgot that the text says "Auras"
Dactylartha, also many thanks! I think the idea with some top deck manipulation regarding lands might be good as ramp (
Courser of Kruphix and the likes), I am going to
peek into your decklist to have an idea.
Regarding ramp and card draw, after building so many decks over the last 7 years, it is kind of my template at first. 30 Lands + mana cost of the commander (is 4, so 34 lands) and the rest is ramp until I get to 50 cards (51 with the commander). Then 10 card draw cards at least, and from there on, I modify it depening on how the deck behaves.
