Game plan
Hit with neheb between turns 3-5 -> win the game.
Let me show you an average 5th turn win estimate.
turn 1-land pass
turn 2-land pass
turn 3- land pass
turn 4-land play neheb pass
Turn 5-DONT PLAY THAT LAND before neheb does his shit. Now you have eight cards in hand. Use one of the like 11 doublestrike instants/sorcs in the deck on neheb.
Hit with neheb, have access to 14 mana and/or 14 more cards that runs you into a win con/ more ramp/ more card draw.
what? didn't draw any of those in 26 cards? Understandable. Play one dragons approach since... you must have gotten 4 in the graveyard now right? tutor out knollspine dragon and draw 13 more cards. in those 39+ cards of a deck filled with wheels, ramp and graveyard recursion you pretty much go nuclear. there's around 10 different cards that can be treated as win con's in of themselves.
Oh what you have a sol ring/vault opener?
You do all this on turn 3 and win the game on turn 3 instead.
what after all of that you still don't have a win angle? there is 3 extra turn spells for 2 mana in this deck(last chance, warriors oath and final fortune) after taking that extra turn if you can't win then it isn't the decks fault. It's either bad piloting, generationally bad luck and/or blue players.
