This is the very first deck I started with when I began playing MTG. I found the indestructible mechanic here on tapped out and ran with it. After 2 and a half years of play testing and modifications I've finally settled on what I think is the best foundation for my play style. This deck works best in a 2HG setup as you have more time to get setup but is viable in a 1v1 in my limited experience. I am by no means a deck builder as this is my first build. Any feedback or suggestions are very much welcomed!
Ensoul Artifact is the key here. Place it on an Ornithopter or a Darksteel Relic to swing by turn 2 for 5. You can also place it on any other Indestructible card in the deck such as Darksteel Citadel, or Mistvault Bridge and still swing for 5 by turn 3.
Copy Enchantment just ramps this up further as you get more Indestructible permanents out naturally every turn and can convert more and more of them into indestructible 5/5's.
Apply a Cranial Plating and a Spectral Flight on of of your indestructible creatures and swing for insane amounts of damage early game.
Or use Bident of Thassa to make your opponents attack you with everything they have essentially field wiping if you have the creatures to block. If you have the Mirage Mirror out you may copy your creatures until end of turn to further build your wall against this forced attack or use them for fodder for big creatures you cannot kill yet.
Does your opponent have creatures you cant overcome? Use Protean Thaumaturge to copy it while you Ensoul or copy one of your artifacts!
Since the average CMC of this deck is so low it allows you to almost hand dump every turn. Combine this with draw power from Ancestral Vision and Bident of Thassa, you will almost always have something extra coming up to play or to have as a backup.
Ignore the maybeboard. Those are cards I've experimented with in the past that have worked ok. But I'm still unsure if they have a place or not.
I am considering removing 2x Mistvault Bridge in lieu of 2 other useful non-basic lands. Maybe Buried Ruin?
