Hello, sorry i don't see anything on the link you gave us but i'm playing that type of deck in izzet so if you give me the color maybe i could give you some advice.
#Card draw deck?
frail vector
young estuary
It’s in grixis
so blue blaxk red
also no need to be sorry you're completely fine
timber flower
needs more wheels imo
id also reccomend going kess, and putting nekusar in the 99
you get targeted less, and wheels can get casted twice, feeding kess more
when you have a large graveyard just [[mizzix-mastery]]
lyric ledgeBOT
Sorcery
Exile target card that's an instant or sorcery from your graveyard. For each card exiled this way, copy it, and you may cast the copy without paying its mana cost. Exile Mizzix's Mastery.
Overload 
(You may cast this spell for its overload cost. If you do, change "target" in its text to "each.")
timber flower
and win
young estuary
okay ty very much
pure birch
Command tower
young estuary
Idk how I completely blanked that xD
