Third turn lightning blitz

[Deathseide]

T1: swamp and {lotus petal} tap swamp and use the petal for {Dark Ritual}, play  {Gravecrawler} and  {Phyrexian Altar}.
T2: swamp, tap for second {dark ritual} and play {lightning coils}. Tap second swamp for second {gravecrawler}.
Begin sacrificing the {gravecrawler} to the altar and recasting, adding counters to the coils, when you have many, many of them, end turn and wait for the beginning of turn 3.
T3:  {Lightning Coils} activates, blitz with the mini ball Lightnings...

You need another zombie to use gravecrawler's ability, so this only works once you have another zombie on the field.

"Tap second swamp for second {gravecrawler}."
I believe that was covered

He has you sac Gravecrawler a lot on turn 2 with no mana open to recast him...

The {phyrexian altar} deals with the mana issue

This combo does not work (on turn three). Lets pretend your opening god hand is swamp,  {Dark Ritual},  {Gravecrawler}, {Lotus Petal},  {Phyrexian Altar},  {Dark Ritual} 2, swamp 2. Even with that you only get 1draw and you need another  {Gravecrawler} and  {Lightning Coils} for the combo sooo no, not the way you described it can't work your way

It does work if you go second, and draw on your first turn.
