Thank you for your comments! Sincerely, a friend lent me a
Hydroid Krasis and I thought it can fit in this deck because normally I have enough lands to make it easily a 6/6 or 7/7, as a blocker or a threat for the rival. This card gave me a win against mono-red aggro in the tournament with the gain-life and vs a sultai-food deck, which was so close, it made me refill my hand giving me a "
chance for glory" (#badjoke).
And about the
District guide, I know it could be used as a early blocker but I rather to choose cards like
negate or
open the gates, or even more
deafening clarion ...
But if you want to know, the more important part of this deck, its the capacity of adaptation, the sideboard.
