GAMEPLAY
Ghalta is all about doing Commander Damage, no matter how much Life a player has, when dealt 21 Commander Damage that player losses.
This deck can easily rebuild after Boardwipes (even after 2 or 3 of them). By getting Ghalta in the Battlefield for 2 Green Mana.
Doing this by storing Creature Power on the Battlefield that you can't really interact with.
Focus on Mana Dorks that cost 1 Green Mana to Cast, like Elvish Mystic.
Ghalta is hard to remove that Combat, so expect Removal Spells, but you Recart the next turn for 2 Green Mana most likely.

GHALTA CASTING COST
Ghalta's X cost reduction covers also the Commander Tax.
Using Vehicles, like Dodgy Jalopy, you Tap 3 Power worth of creatures and the Vehicle boceomes a Creature which reduces the Casting Cost of Ghalta even more (Double Dipping).
Treetop Village, Pay {1}{G} and Ghalta is now 3 cheaper, and you can still tap the Land for 1 Green Mana. Also works with Mutavault.

CREW
A creature with Summoning Sickness can still be used to Crew a Vehicle, this is not considdered a tapping-ability of that creature but a ability of vehicle.
You can use Crewed Vehicle to Crew OTHER Vehicles.
Destroy Creature can only work when the Artifact is Crewed, Destroy Artifact always works.

GHALTA POWERUPS
Surrak,  gives Ghalta Haste. You need Ghalta to hit as fast as possible as you don't have Counterspells to counter creature removal.

CARD DRAW
Life's Legacy, sacrifice Ghalta after you attacked in the second man phase, draw 12 card and recast Ghalta for 2 Green Mana.
