Historic Bo1 Gruul(slightly white-touched) Ponza

This is the RGw Ponza deck constructed mainly around Goblin Engineer. I got Mythic #77 with 23-4 record .

The deck has 10 indestructible artifact lands, which can be sacrificed to Goblin Engineer ability or even be returned to the battlefield with it. There are many cards to be selected to be entombed: Haywire Mite (which got buffed significantly), Liquimetal Coating, Soul-guide Lantern, Circuit Mender (which got slightly buffed) and Phyrexian Dragon Engine (This is the key card for draw engine).

You can entomb one of those cards with engineer depending on your opponent, then return it back with engineer\’s ability, sacrificing artifact lands if needed. Note that it also has a great synergy with Jarsyl: You can entomb 1-mana artifact with engineer then return it with Jarsyl the following turn.

Indestructible Artifact lands? Why not cleansing wildfires? They are the best 2-mana ramping spell which ramps and draws at the same time. They can also be used to clear your opponent\’s transforming lands in the lategame. 

This deck has tons of artifact removals, which can be comboed with Liquimetal Coating which you can get with engineer or Karn. Sometimes they are just great without coating if your opponent is playing Hammer Time or Affinity decks.

Note that Gleeful Demolition can be used to destroy artifacts, but also to make 3 1/1 tokens by targeting your indestructible artifact lands.

Have fun with this deck! Good luck. (If you meet Grixis,  Jund, Rakdos, or Burn decks, you will have to pray..)
